Bagan Medical Clinic Opening
The Bagan Medical Clinic is open throughout the year except for one or two weeks during April because of the Water Festival and Myanmar New Year.
Doctor Hla Tun is also Chief Medical Officer aboard the 'Road to Mandalay' river cruise ship operated by Belmond. During much of the season, this ship shuttles between Shwe Kyet Yet (near Mandalay) and Bagan, mooring at Bagan (close to the Bagan Clinic) from Friday to Monday, whilst the ship's guests explore the wonders of the pagodas spread across the Bagan Plain. This allows Doctor Hla Tun to open the Bagan Clinic on Friday, Saturday and Sunday. Working from 08:30 to 23:00 (with short breaks for food) Doctor Hla Tun typically sees 90 patients each day the Clinic is open. Less complex cases are seen by other doctors.
Free Lunches
A free lunch is served to patients and their companions on the clinic days (Friday, Saturday, Sunday).

Donation of Children's Clothing
Donations of children's clothing are occasionally made to young patients.
Donation of Reading Glasses to elderly patients

Need for translators
Some patients travel long distances from the Delta, Rakhine State and Chin State to the Clinic. Translators are required for some of these ethnic groups because of the local dialects they use rather than standard Myanmar language.
Chin State, in Western Myanmar, is close to the Indian border and a patient from that area required a translator, as she couldn't understand the Myanmar language. This patient had facial tattoos, once common in the area.

New Equipment for Bagan Clinic
In May 2016, the generosity of two Guests funded the purchase of a new dental chair.

Opening of Two Storey Clinic Building
Donors have provided funds for a 2-storey clinic building at the Bagan Clinic.

Individual Patient Stories
A lady who suffered from drooping of her upper eyelids could not afford to buy medicine and so she used tape or plaster between forehead and eyebrow at one end and upper eye lid at the other end to open her eyes. She was treated with eye drops.

In the previous update on Bagan Clinic here, we reported donations of anti-snake venom to hospitals. A particularly tragic case involving a snake bite concerns a lady from Chauk who earns a living collecting plums from under trees. Whilst collecting plums from a hole in the ground, she was bitten by a cobra. The local hospital injected anti-snake venom then she continued treatment with traditional medicine but developed a necrotic ulcer with exposed bone. Relatives and friends gave her money for transportation to Magway Divisional Hospital (about four hours away) for wound debridement treatment but she could not afford the transport costs for the necessary 3 or 4 follow-up treatments. Instead, she attended Bagan Medical Clinic where the cost of transport for further treatment at Magway (the equivalent of 8 Dollars U.S. per trip) was donated.

Special Medical Clinic Opening
On Monday, 26th September 2016 the 'Road to Mandalay' ship was 'stopped' at Bagan for a week, giving the Doctor the opportunity to open the clinic for a whole week. On the evening of Sunday 25th September, there were still some 350 patients waiting at the Clinic. Appointments were made for these waiting patients to return on a specific day to receive treatment. Patients who had travelled long distances were temporarily accommodated in the Bagan Monastery or at nearby monasteries. The Bagan Monastery was able to provide a free lunch every day and at least one free breakfast and one free dinner but patients accommodated elsewhere had to buy breakfast, lunch and dinner each day for up to five days, adding to the cost of their visit.
One couple from a remote area had borrowed money for food whilst waiting against the security of their gold ring but, when Doctor Hla Tun discovered this, he gave them the money to recover their ring.
Depending upon the distance travelled to reach the Clinic, transport can cost the equivalent of 5 - 20 Dollars U.S. per person and it's common to hear of a pig, goat, chicken or duck being sold to pay for transport.
During this week, Doctor Hla Tun asked a group of old ladies, who waited four days for treatment, why they had not gone back to their village about 50 miles away and returned on the day of the appointment. Their answer was that, once they'd paid to go home, they would be left with no money to return to the Clinic. Most of the group suffered from joint pain but the waiting additionally produced colds and coughs.

As I wrote in the post 'Single-Wheeler' locomotives, early locomotives for passenger trains tended to have just a single-pair of driving wheels. This made the mechanism simpler and more free-running. Locomotives like 'Rocket' and the 'Planet' class had a single pair of moderately-large driving wheels to achieve fairly high-speed running on passenger trains. There's a little more in the post 'Planet' in Perspective, which outlines the use of four coupled wheels for freight locomotives where load haulage was more important than speed. There's much more about the history of the 'Planet' class (and the modern replica locomotive at the Museum of Science and Industry in Manchester) here.
Later designers used even larger driving wheels to achieve higher speed without increasing piston speed. But large driving wheels required great skill on the part of the driver to get trains started under less than ideal conditions without excessive slipping.
Patrick Stirling of the Great Northern Railway remained a staunch advocate of 'Singles', such as his famous class of 4-2-2 engines with 8 foot 1 inch diameter driving wheels, introduced in 1870.

Preserved Stirling 4-2-2 displayed at Doncaster in 2003 (Photo: Our Phellap).
When Dugald Drummond was at the Caledonian Railway, he too produced very successful 'Singles', like the 4-2-2 '123' with 7 foot drivers built in 1886.
Preserved Drummond 4-2-2 '123' (Photo: Glasgow Museums).
The growth of passenger demand meant that there was continual pressure to increase the loads hauled and many locomotive designers turned to four-coupled designs, where the torque delivered to the two wheels of the driving axle by the connecting rods was shared, through coupling rods, with a similar pair of wheels which became 'coupled wheels'.
The locomotive designer Patrick Stirling was not convinced, famously claiming, in his Scottish accent, that "A coupled engine is like a laddie running with his breeks [trousers] down". Certainly, the success of coupling wheelsets together depends upon the accuracy with which the crankpins are set, referred to as 'quartering' - inaccuracies will produce a 'stiffness' in the mechanism which may be tolerable in a freight engine not expected to travel at high speed but is unacceptable in an express design.
In the early days of locomotive building there were problems in achieving the desirable accuracy but by 1896, when Johnson produced his handsome '115' class 'Singles' for the Midland Railway, production techniques had evolved sufficiently for the four-coupled passenger locomotive to have become common. Johnson's later designs for the Midland featured the 4-4-0 wheel arrangement which persisted for express locomotives on the Midland and L.M.S. until the Stanier era.
Dugald Drummond
Dugald Drummond (1840-1912) was born in Ardrossan and served an engineering apprenticeship in Glasgow before gaining further exoerience on Scottish railways. After managing the Birkenhead boiler shop of Thomas Brassey, in 1864 he moved to Cowlairs railway works under Samuel Waite Johnson (later of the Midland Railway). He then became Foreman Erector at the Inverness works of the Highland Railway under William Stroudley. When Stroudley moved to the L.B.S.C.R., Drummond followed as his assistant before taking up the post of Locomotive Superintendent of the North British in 1875. In 1882 Drummond moved to the Caledonian Railway before an unsucessful private locomotive building venture in Australia, followed by a time back in Scotland at the Glasgow Railway Engineering Company. He was Locomotive Engineer (later titled Chief Mechanical Engineer) of the London and South Western Railway from 1895 until his tragic death in 1912. He appears to have been outspoken and difficult throughout his career but is recognised as an important locomotive engineer.
His younger brother, Peter, also had a significant career as a locomotive designer.

The Drummond 'T9'
In the 'C8' class, Drummond designed an inside-cylinder 4-4-0 with 6 foot 7 inch diameter coupled wheels and a 9 foot coupled wheelbase, similar to earlier designs he'd produced for the North British and Caledonian railways. The 'T9' which immediately followed was intended to increase steaming capacity by lengthening the coupled wheelbase to 10 feet, allowing a larger grate. In Scotland, Drummond had learnt the value of rugged, reliable construction and the 'T9' embodied these principles with 1 inch thick steel frames. Between 1899 and 1901, 66 engines were built in three batches, paired with either a 6-wheel or 8-wheel 'Watercart' tender. Early engines featured a narrow cab and in addition to normal splashers on the coupled wheels which incorporated sandboxes, smaller splashers were provided to clear the coupling rods and crankpins. The third batch of engines built had wider cabs with matching splashers, removing the need for coupling rod splashers and conventional sandboxes were substituted. Vacuum brakes were standard (although at least two had air brakes as well).

Drummond had acquired from Stroudley a dislike of unnecessary boiler piercings so the two lock-up safety valves were placed atop the dome - a very distinctive feature. Drummond was not enthusiastic about superheating but he did increase the boiler working pressure on the 'T9' to 175 p.s.i. Enginemen were then encouraged to adjust the 'cut off' to achieve best economy by using the steam expansively. Drummond was an "engineman's engineman", familiar with work on the footplate, although his demeanour could be fierce. He gave lectures to footplatemen at a number of sites. These lectures were later published as a pocket reference book.
The Drummond arrangement of Stephenson Link Motion operating slide valves was regarded as particularly successful and free-running. The fitting of a steam reverser made frequent adjustments to the 'cut off' an easy task.
Eastleigh drawing E34 below shows the original appearance of the first batch of twenty locomotives, built at Nine Elms.

Although Drummond did not embrace superheating, he was anxious to maximise steam generation and he introduced various water tube arrangements to his boilers. The second batch of thirty 'T9', built by Dubs (there's a short history of Dubs here) incorporated two groups of water cross tubes in the firebox. With or without water tubes, the class performed well.
In 1922, Urie rebuilt number 314 with an Eastleigh pattern superheater, extended smokebox and stovepipe chimney. Subsequently, the rest of the class received these changes, generally giving the appearance shown in Eastleigh drawing E34B below. After 1925, the Maunsell superheater replaced the Eastleight pattern.

The T9 was liked by enginemen and came to be regarded as Drummond's 'masterpiece'. The class had a long life - none were withdrawn until the 1950s and the last (number 120 from 1899, renumbered 30120 by British Railways) survived until 1963 when it became part of the National Collection managed by National Railway Museum.
On Saturday 8th April 2017, I finally got to drive the National Collection's 'T9' at the Battlefield Line. But that's another story.

Once the 2016 'Santa Specials' were over (there's a brief report here), railway operations ceased for two months of 2017, giving the volunteers who work on permanent way maintenance an opportunity to prepare the route for the 2017 season.
Peak Rail Working Volunteers Lunch
My first trip to the Matlock area in 2017 was on Saturday, 18th February when I didn't get beyond Matlock Bath. I was attending the Peak Rail Working Volunteers Lunch which was held at the elegant Matlock Bath Hotel. As this engagement didn't involve the usual pre-dawn start needed when I'm rostered for the footplate, I travelled by train. There were existing photograph albums covering part of the route I took, from Wolverhampton to Birmingham New Street, then on to Derby. These albums are West Midland Railways and Derby - Birmingham. The last leg of my journey was by East Midland Trains single unit DMU to Matlock Bath, one station before the last stop at Matlock. I've added a new album Derby - Matlock to cover this area.

The effort involved by working volunteers in running an operation like Peak Rail could be judged from the crowded dining room. In addition to the convivial lunch, Peak Rail Management took the opportunity to update members on some of the developments in hand.

Peak Rail Volunteers' Lunch: 18-Feb-2017
Events of Sunday, 26th March 2017
Saturday and Sunday services re-started in March, with a timetable of four top-and-tailed services between Rowsley and Matlock Town.
My first driving turn of the year was on Sunday, 26th March. This time, it was an early start, made worse by the clocks going forward an hour on Saturday night. So my alarm had to be set for 3.0 a.m. when I retired which, of course, would be 4.0 a.m. when I got up on Sunday morning.
The motive power was 'Jennifer', an outside-cylinder six-coupled Hudswell Clarke side tank, built the same year that I was born. With Mike S. as Fireman and Jacob as cleaner, we were ready to come 'off shed' at 8.30 a.m. ready for two one-hour Driving Experience Courses before taking the first service train at eleven o'clock. The combination of outside cylinders and the characteristics of the drawgear had been found to cause oscillations at some speeds so an instruction was in place that 'Jennifer' should not exceed 15 miles per hour.

I used the first trip to experiment with methods of driving to try to minimise the 'surging' effect, particularly since the 'Palatine' Restaurant Cars were being 'laid-up' by waiting staff for the diners who would board before the second round trip to enjoy the Mothering Sunday Lunch. This season, the beautifully-restored L.M.S. coach 7828 forms the main dining coach of the 2-car dining set.

'Jennifer' proved a strong engine and a free-steamer and we completed the day without additional difficulties.
Events of Sunday, 2nd April 2017
Just a week later, I was back again, this time with Dave P. as fireman but with no Cleaner, starting the day with a two-hour driving experience before 'hooking onto' our train. Normally, it's good practice to tighten up the screw coupling between engine and train leaving two turns of thread visible on either side but, in order to provide as much buffer compression as possible to limit the tendency to 'surge', we tightened the screw fully and it seemed to help.
Now we were into April, the timetable called for five top-and-tailed services between Rowsley and Matlock Town, which we completed without problems.

Events of Wednesday, 6th April 2017
Three days later I was back yet again because April also introduced a service on Wednesdays. Keiron was firing with John M. as our Cleaner. At 08:45 we started the first of two 1-hour Driving Experience Courses, leaving us very little time before taking the first service train at 11:00. During the day, further experiments were carried out on the coupling between locomotive and train. I was sure that the use of the engine coupling onto the coach drawhook would be tighter than the other way round (coach coupling onto engine drawhook), and so it proved. But we also tried the Emergency Coupling which is kept in the Guard's compartment. These have a D-hook on both sides of the screw and are used to connect the two drawhooks, as the name suggests, in emergency. However, this offered no improvement so we reverted to the engine coupling onto the coach drawhook with the screw fully tightened. The weather was warm all day and we were gratifyingly busy for a mid-week steaming. Incidentally, there's a short description of the business of hooking a locomotive onto a passenger train in the post On the Footplate (Part 2). At the end of an enjoyable day, Keiron coaled the engine using the bucket loading shovel and 'Jennifer' was stabled in the shed. The method of disposal varies from railway to railway and from locomotive to locomotive but an idea of what's involved can be gained from the post MIC - Disposal.

The East London Line has a fascinating and varied history which I'm afraid I had almost completely overlooked until my firm became involved in supplying replacement Tunnel Telephone equipment for the section of the line which passes through the Thames Tunnel.
The Initial Vision
The rapid growth of London and its docks gave rise to a need for better communication across the Thames but early attempts to construct a tunnel met with difficulties owing to the geology. Marc Brunel (father of the better-known I.K. Brunel), having patented a 'tunnelling shield', obtained finance in 1824 for the ultimately-successful project to build the Thames Tunnel. The project suffered a succession of problems and Marc's 20-year old son Isambard became involved and was awarded a silver medal by the Royal Humane Society in 1828 for his bravery in saving lives during serious floodings of the workings (Royal Humane Society Report). Eventually, in 1843, the tunnel was completed as a twin tunnel with frequent cross-passages between Wapping and Rotherhithe. A plaque erected by London Transport at Wapping Station announces the tunnel's pioneering status:-
The tunnel which runs under the Thames from this station was the first tunnel for public traffic ever to be driven beneath a river.
It was designed by Sir Marc Isambard Brunel 1769-1849 and completed in 1843
His son Isambard Kingdom Brunel 1806-1859 was engineer-in-charge from 1825 to 1828.

Commemorative plaque in Wapping station.
The cost overruns meant that approach ramps allowing the tunnel to be used by horse drawn carriages as originally intended could not be financed so, by placing stairways in the construction shafts on either side of the river, the tunnel was opened only to pedestrians. It was not a commercial success, despite becoming a major tourist attraction with numerous stalls in the tunnel selling souvenirs.

The building at Rotherhithe which originally housed the pump for the Thames tunnel is now The Brunel Museum Thames Tunnel, with a website here.
Conversion to railway use
Although the Tunnel had not achieved its aim of providing a cross-river link for horse-drawn vehicles, its dimensions allowed it to be adapted for rail traffic and, in 1865, the tunnel was purchased by the East London Railway. This was a joint venture by six railways hoping to profit from better freight and passenger connections across the river:-
Great Eastern Railway
Metropolitan Railway
District Railway
London, Brighton & South Coast Railway
London, Chatham and Dover Railway
South Eastern Railway
(The last three railways ultimately formed part of the Southern Railway and there are brief histories of these lines in two posts 'Origins of the Southern Railway' listed in 'Related posts on this site' below).
With Sir John Hawkshaw as engineer, the tunnel was converted and approaches built allowing its use as a double-track railway which was extended on both side of the Thames with a number of stations and making connections with the participating railways. The work was carried out in stages and completed by 1884.
The Great Eastern terminus at Liverpool Street was the northern extremity of the East London Line passenger service. Rather inconveniently, freight trains to and from the Great Eastern had to reverse at Liverpool Street. Alternately, there was provision for transferring wagons (two at a time) a hoist at Spitalfields. North of the river, stations were provided at Shoreditch, Whitechapel, Shadwell and Wapping. South of Whitechapel station, St. Mary's Curve provided a connection to the route operated jointly by the Metropolitan and Metropolitan District railways.

South of the river, the line passed through Rotherhithe and Deptford Road stations before dividing into three branches which joined the L.B.S.C.R. South London Line to Victoria, the L.B.S.C.R. Croydon and Brighton Line from London Bridge and the S.E.&C.R. line from London Bridge.

The well-known 'Brighton Terriers' were one of the locomotive types commonly used on passenger trains on the East London Line.

London Underground
In 1933, the East London Line was taken over by the London Passenger Transport Board and was operated by London Underground. Between Shoreditch and two southern termini at New Cross Gate and New Cross gate the line was electrified using the standard Fourth Rail Electrification arrangements (as outlined in the post here) and Metropolitan Line rolling stock based at a depot at New Cross. When heavy repairs were required, the trainsets travelled to Neasden, accessing the main Metropolitan route using St. Mary's Curve. Freight trains continued to use the line until the 1960s. Apart from a morning and evening 'rush', the East London Line was fairly quiet and it continued as a rather 'forgotten line'.

A modern mural at Wapping showing a Northbound electric train arriving at Wapping station, passing a freight train.
Temporary closure in 1995
In 1995 the line was completely closed to allow repairs to the Thames Tunnel itself and the building of an interchange station at Canada Water with the Jubilee Line which was being constructed. The use of 'shotcreting' in the Thames Tunnel proved contentious and a short section was preserved as-built. The repair work included replacement of the elderly Tunnel Telephone system required on the underground sections of the line and my firm supplied the new equipment. In 1998, the East London Line re-opened, continuing the earlier services from Whitechapel (Shoreditch during the 'rush') and either New Cross or New Cross Gate.
London Overground Era
In 2007, the London Overground had taken over operation of a number of mainly North London services including Euston to Watford, Clapham Junction to Willesden, Stratford and Barking. More ambitious plans were accepted to add an extended and modernised East London Line to the London Overground Network. The East London Line closed again in 2007 allowing re-signalling, station upgrades and building of a depot for the new trains at New Cross Gate. The electrification system was converted to third rail 750 volts d.c. and the technical changes necessitated replacement of the Tunnel Telephone equipment on the East London Line which, again, my company supplied.
Rolling Stock
The London Overground is operated by various versions of Class 378, built by Bombardier at Derby. There were originally three variants - 378/0 3-car, 378/1 4-car d.c. and 378/2 4-car a.c./d.c.

Newly-built Class 378 at Bombardier, Litchurch Lane, Derby in 2009.
East London Line re-opening
The East London Line re-opened in 2010 with modern, full-size trains through the Thames Tunnel from Highbury & Islington in the North to New Cross and, via New Cross Gate and existing Network Rail lines, to West Croydon and Crystal Palace in the south. I travelled on part of the new line in June 2010 and there's a short post here.

London Overground Expansion
The new services have proved popular. There are now 57 trainsets - the 378/0 were converted to 378/1 and both 378/1 and 378/2 have been augmented to 5-car sets in an attempt to meet increased demand, necessitating elective door opening at certain East London Line stations with short platforms.
The abandoned connection south of Surrey Quays with the former South London Line has been re-instated (with a grade-separated junction at Silwood Junction, South of Surrey Quays), adding a service via the Thames Tunnel to Clapham Junction. With change of trains, the London Overground now provides a 'ring' service around London.

Introduction
Passenger trains through the Channel Tunnel to and from London were inaugurated in 1994. Although high-speed trainsets were used (the 'Trans Manche Super Train' or 'TMST') running within Britain was initially rather pedestrian, being confined to existing, conventional third-rail electrified lines. I was never tempted to try out this service.
Eventually, in 2003, section 1 of the U.K's first high-speed line ('High Speed 1' or 'HS1') was opened so, having made fairly leisurely progress from Waterloo International to Fawkham Junction, a few miles beyond Swanley, Eurostar trains diverted onto the new high speed line, allowing speeds up to 186 m.p.h. I still didn't make a high-speed trip or travel through the Channel Tunnel.
However, my firm became involved with the 'TMST' trainsets when the British form of an Automatic Train Protection ('ATP') system was introduced. This APT combined the traditional Automatic Warning System ('AWS') with a new Train Protection and Warning System ('TPWS'). I helped with various elements of the design and validation of the equipment installed on the 'TMST' trainsets (by this time known, more prosaically, as 'Class 373') and, in 2005, I had the opportunity to travel on a Class 373 Test Train on the East Coast Main Line to assist with equipment testing. That trip is described here which includes a little more about the background to TPWS in the section 'The Introduction of TPWS'.
Test Train on 17th January 2006
A few months after the Grantham trip, I was able to travel on a Class 373 Test Train from Waterloo International to Paris (Gare du Nord) which travelled from Waterloo International to Fawkham Junction on conventional, third-rail electrified lines before continuing on section 1 of 'High Speed 1' through the Channel Tunnel and on to the Gare du Nord in Paris.

Since test trains carried no passengers, they earned no revenue so understandably the operator, Eurostar, only reluctantly scheduled such trips. However, we had learnt that a software update for the traction control was to be tested between London and Paris on an international test train and we 'piggybacked' on this to be able to carry out further testing of the equipment we'd evaluated on the earlier trip to Grantham. We would only be able to conduct full tests between Waterloo and Fawkham Junction - beyond here on High Speed 1, in the Channel Tunnel and on the continent, the TVM cab signalling system would be in use. However, we continued to monitor our equipment in case of any anomalies.
Our equipment was set up in the equipment room just behind the front cab and we were kept pretty busy between Waterloo and Fawkham Junction checking for correct responses from the equipment which were also being saved by a recording multi-channel oscilloscope for subsequent analysis. I noticed that the cab itself was fairly full on the way from Waterloo to High Speed 1 with traction control engineers but, as we approached the Channel Tunnel, they all went back to the leading passenger coach where their test equipment was set up.
So I was able to join the friendly English driver throughout our undersea journey and a fair distance towards Paris. He apologised that he couldn't quite travel at 186 m.p.h. because one of the traction control blocks had 'tripped', reducing the top speed, but I think we were still doing around 160 - 170 m.p.h. I was surprised at what little sensation of high speed there was as we dashed through the French countryside. In high speed trains, the driving position is intentionally on the centre line of the train and the front window is surprisingly narrow, to minimise the distracting 'flicker' produced by passing Overhead Line structures and, in the tunnel itself, the frequent tunnel lighting luminaires. I'm afraid I didn't manage any photographs on the way to Paris.
In Paris, I didn't even alight from the train. We only stood for a few minutes whilst the traction engineers checked their test equipment and reset the tripped traction control block, allowing us to return at 186 m.p.h. (300 k.p.h.) where authorised. On the way back, we were in the 'back cab', which we had to ourselves. On the way back, I did manage a few pictures which are in the album Channel Tunnel and High Speed One.
Once clear of the suburbs of Paris, the line is remarkably straight across the plains of northern France and we were running at full speed.

Sooner then I anticipated, we were plunged into the Channel Tunnel (the only trouble with being in the 'back cab' is you can see where you've been, but not where you are going). I couldn't resist a picture of me 'in the chair' in the blackness of the Tunnel.

My attempt at a "driver's view" wasn't very successful, but you can just make out tunnel lighting which is always illuminated.

After 22 miles of blackness, we popped into daylight again, passing several high-speed turnouts which divert the car shuttle trains onto the their reversing loop and unloading/loading station. Tall fences flanked the high-speed line.

We were now travelling on the first section of High Speed 1 (at this date, the final section to St. Pancras International was still under construction). We by-passed Ashford International station (shared with conventional trains) by taking the concrete viaduct, allowing us to maintain our impressive speed.

At Southfleet Junction, we left the continuation of HS1 to London, still under construction, on a high-speed turnout provided with a 'swing-nose' crossing. Having decelerated, we joined the conventional third-rail electrified network at Fawkham Junction, continuing to Waterloo at a very sober pace.

It was dusk as we approached London Waterloo and passed a Down 'Eurostar' service.

Our train, with just a handful of engineers aboard, pulled into platform 24, next to an already well-loaded International service awaiting departure from platform 23. I'd had a fascinating trip.

Completion of the U.K. High Speed Route
Finally, in 2007, the complete 'HS1' was brought into use, terminating at St. Pancras International as the new London terminus and with the servicing of the high speed trainsets moved to a new depot at Temple Mills. Although I'd briefly looked at the St. Pancras terminal in 2008 (there's a post here), I still haven't made a trip on the new route to Paris, but I have been as far as Ebbsfleet International on a Class 395 trainset, as described in the post Channel Tunnel Rail Link.

Channel Tunnel and High Speed One.
Introduction
It always seemed daft to me that the U.K. were involved in the Channel Tunnel Project (completed 1993), built a posh new London terminus at Waterloo International (opened 1994), acquired a fleet of French-designed high speed trains capable of speeds of 186 m.p.h. called TMST (Trans-Manche Super Train) and then ran these new trains for years on ancient third-rail electrified lines already congested with traffic. The complex new trains operated by Eurostar were introduced in 1993 and classified Class 373 in the UK. They could operate from 750v d.c. third-rail in England or from a number of overhead a.c. voltages. Various control systems were fitted including signalling systems TVM and KVB for use in the Channel Tunnel and in Continental Europe but only AWS was initially required to run on conventional lines in the U.K.
Class 373
The fleet of Class 373 was initially split into two types - 'Three Capitals' (to handle London-Paris and London-Brussels services) and 'North of London' (to deal with proposed feeder services within the U.K.). Trial running North of London was not encouraging - the existing electrified routes had difficulties supplying the new power-hungry trains and interference with signalling systems was problematic. As a stop-gap, conventional feeder trains, not available to ordinary passengers, were run to Waterloo to connect with services through the Channel Tunnel. I once managed to 'hitch' a ride from Wolverhampton to Birmingham on one of these restricted services from Manchester when the normal service was disrupted and I knew the Train Guard. This was a locomotive-hauled train with the coaches retro-fitted with central door locking. Load factors were disappointing on these feeder services, which were soon discontinued.
The enterprising GNER franchise leased some of the spare 'North of London' sets and, following the technical approval phase, managed to operate a service between King's Cross and, I think, York. At least some of the GNER sets were re-painted in dark blue, which suited them very well.
Raising speed from the Channel Tunnel to London
The Channel Tunnel Rail Link, also called 'High Speed 1' as the U.K's first high-speed line linking the Channel Tunnel to London, was built in two sections. The first section, opened in 2003, allowed high speed running at up to 186 m.p.h. between the Channel Tunnel and the Southfleet Junction (a little south of Gravesend) using the TVM signalling system. After an interchange section to Fawkham Junction (on the existing Swanley to Rochester lone) Eurostar trains then continued to Waterloo International station in London on third-rail d.c. electrified lines. In 2007 the second section of 'High Speed 1' was completed from Southfleet Junction to St. Pancras International, allowing maximum speeds of 140 m.p.h. The existing St. Pancras station required complete re-furbishment and a new station was built at the north end of the site to handle domestic trains and the extreme length of the International trains. Waterloo International became redundant after less than 14 years use. Although Waterloo International is slowly finding new uses, its design is not well-suited to handling domestic services. Incongruously, for a time a dramatisation of 'The Railway Children' was successfully staged in the International Platforms. In addition, the purpose-built North Pole International Depot which had serviced the Class 373 since their introduction had a rather short initial working life. It was not conveniently situated for providing trains to the new terminus at St. Pancras International so a new maintenance depot at Temple Mills replaced the original one at North Pole.
The Introduction of TPWS
Accidents such as Southall and Ladbroke Grove had focused attention on the limitations of the Automatic Warning System (AWS) used in Britain. It was not (nor intended to be) an Automatic Train Protection (ATP) system, since it could be over-ridden by the driver. Various schemes were afoot in Europe but, in an attempt to plot a course that was both affordable and achievable in a reasonable time-frame, the Joint Enquiry into Train Protection Schemes (available here concluded that a plan to supplement AWS with a Train Protection and Warning System (TPWS) should be implemented. All locomotives and multiple units, including Class 373, had to be fitted with TPWS in addition to AWS. There's an RSSB publication about these systems here.
Test Train on 6th October 2005
When I was writing about a trip on the Channel Tunnel Rail Link in early 2017 (Channel Tunnel Rail Link), I was reminded of an earlier trip on a Class 373 Test Train in 2005 which I have described below. The following is very much an historical account: since I became involved in the design and validation of some of the new equipment for Class 373 in 2005, so much has changed. I had one opportunity to travel on a special Class 373 Test Train from North Pole to King's Cross then to Grantham and return when I assisted with the tests being carried out. Arriving by road with our test equipment at North Pole, we found depot security quite tight but eventually lugged our gear onto the waiting train. Leaving North Pole International Depot we had to take an intriguing route across North London to King's Cross before we could start the proper test run to Grantham. We were using a recording multi-channel oscilloscope to collect data about the response of various sensors at different speeds.
North Pole International Depot to King's Cross
The Depot had four Reception Sidings (actually bi-directional) diverging from the Down West London Line and one Departure line (also bi-directional) which passed under the West London Line and trailed into the Up West London Line at North Pole Junction. Whilst these connections were convenient for getting to and from Waterloo, our train needed to head in the opposite direction to get to the East Coast Main Line. Having driven the train out of the Depot and south of North Pole Junction, the driver had to change ends before continuing. Whilst we made our way to King's Cross, I was involved in helping to set up and check the test equipment located just behind the 'active cab', so I couldn't pay much attention to our interesting route on the way out. We crossed over the Great Western Main Line before turning left at Mitre Bridge Junction, crossed over the West Coast Main Line at Willesden Junction High Level, crossed over the Midland Main Line at West Hampstead, turned right at Gospel Oak to join the North London Line at Camden Road. Here, we took the single North London Incline and joined the Down Slow of the East Coast Main Line, continuing to Finsbury Park where the driver had to change ends again. We set off and crossed to the Up Slow for the short journey to King's Cross. Now the equipment was set up and we were in the 'back cab', I was able to take a few pictures of the rain-swept railway.

At Holloway Junctions, we were switched to the Up Fast and then the Up Slow passed over us on a flyover, just north of Copenhagen Tunnels. This arrangement transposes the four running lines from Up Slow, Up Fast, Down Fast, Down Slow to Up Fast, Down Fast, Up Slow, Down Slow. This gets the stopping trains using the Slow Lines onto the west side of King's Cross, handy for Suburban platforms 9, 10 and 11. There were formerly three double-track bores forming the Copenhagen Tunnels but the East Bore is now disused. South of Copenhagen Tunnels, all four running lines become reversible and we were switched to the adjacent line which forms the Down Fast further north but is designated 'Number 1 Fast' here. I spotted the North London Incline we'd used earlier to access the East Coast Main Line before we were plunged into the 528 yard Gasworks Tunnels which were also formerly three double-track bores before the East Bore was abandoned.

We stopped in platform 6 and, of course, the driver changed ends once again. Before we set off, I managed to take the picture below from the leading cab before concentrating on the testing we carried out as the train sped northwards to Grantham.

King's Cross to Grantham
I was kept pretty busy monitoring the testing on the Down journey to Grantham. I'm not sure of the Line Speed Limit at the time, but we were batting along and passing signals frequently so there are no photographs recording the trip. We had a slight problem with the test gear at one point but, other than that, we collected plenty of useful data to be analysed later. It was still raining when we stopped at Grantham.
Grantham back to London
As soon as the driver had changed ends, we set off back to London, crossing to the Up Line on the crossover south of Grantham station. We were not carrying out active tests this time, as we were now at the rear of the train, so I was able to take a few pictures as we hurtled south.

After the 880 yard Stoke Tunnel, the route became 4-track 'paired by direction' and we passed the site of "Mallard's" record breaking run.

We reeled off another twenty miles at speed to reach Spital Junction, Peterborough.

We took the Up Fast through Peterborough station and passed under the distinctive girder arch bridge which takes Thorpe Road over the railway.

South of Hitchin, I was on slightly more familiar ground as, back in 1974, my firm had installed an Electrification Telephone system for British Rail between Hitchin and King's Cross. This is briefly mentioned in the post Electrification Telephone Systems for British Rail. Just north of Wood Green (the station is now called 'Alexandra Palace') we passed the flyover junction leading to the Hertford Loop.

We were routed onto the Up Slow at Finsbury Park, continuing on the Up Slow Flyover into the West Bore of Copenhagen Tunnels. At lowered speed, we took the crossover to the Down Slow and, emerging from Copenhagen Tunnel, diverged onto the North London Incline.

I noticed that construction work in connection with the various new connections to St. Pancras International was well advanced.

The North London Line is on the left, with both third rail and overhead electrification. Camden Road East Junction is in the left background.
Our Test Train joined the North London Line at Camden Road Central Junction, and passed through the station where passengers were waiting for an expected Eastbound train at modest speed. After passing Camden Road signal box (since abolished) we diverged onto the branch to Gospel Oak.

We passed through Gospel Oak and continued fairly slowly to Kensal Green High Level Line Junction where we were routed onto the middle one of the three diverging routes.

Our route took us through Willesden Junction High Level station and the bridges over the West Coast Main Line. At Willesden High Level Junction signal box (since abolished) we took the sharply-curved Down High Level Line to Mitre Bridge Junction where we joined the Up West London Line, coming to a stand south of North Pole Junction.

After the driver changed ends for the final time, we made our way into the Depot, using the reversible Departure Line. We unloaded our test equipment and left the Class 373 after a productive and fascinating trip.
