The torque converter rail from the transmission of D1010 ‘WESTERN CAMPAIGNER’ was shipped to a specialist engineering firm for disassembly on Tuesday 25th January 2022. The transportation cost was very kindly sponsored by West Country firm WRINGS TRANSPORT and we are very grateful for their help. Photo by Terry Deacon © CC BY-NC 3.0
Headlining this week is the long-awaited move of the torque converter rail from the transmission of Class 52 D1010 ‘WESTERN CAMPAIGNER’ which has now been delivered to a specialist engineering firm for disassembly. This is a major step forward in the resolution of an issue that occurred during the first day of the 2018 Diesel Gala when the ‘B’ end transmission seized and the loco had to be withdrawn from service.
The transfer of power from the diesel engine to the wheels of a diesel-hydraulic locomotive is handled by the transmission, which in the case of the Class 52 ‘Westerns’, comprises three torque converters (a specialised form of a turbine), each intended for use during a different speed range. The three converters are attached to a hollow shaft that revolves around the central shaft, the whole assembly involving eight bearings and their associated fluid seals, each of which has to be removed, inspected and replaced if necessary.
D1010 – cross-sectional drawing of the Voith L630rV three-stage hydraulic transmission, as used in the Class 52 ‘Westerns’. This is a photograph of a Voith drawing dating back to 1962.
Although the use of hydraulic transmissions on mainline locos was discontinued by British Railways in the 1970s, this form of transmission has lived on in all of the second generation diesel-multiple-units (DMUs) such as Sprinters, Super Sprinters and Turbostars, where the original claims of low weight and high reliability have been fully proven, with many thousands of such transmissions in daily service around the world.
Following disassembly, the parts from D1010’s transmission will be returned to Williton for each of the separate parts to be cleaned, inspected and measured. Then, the spare parts will be ordered and upon receipt of the parts, the whole kit will go back to the subcontractor for assembly. This process is likely to take 6 to 9 months, during which time we will continue to progress with other aspects of the loco restoration project.
We are very grateful to all who donated and continue to donate towards the D1010 RESTORATION APPEAL and we would particularly like to thank WRINGS TRANSPORT for sponsoring this move. Thank you very much indeed !
VERY IMPORTANT DATES FOR YOUR DIARY – the WSR’s 2022 DIESEL GALA will take place from Thursday 9th through Saturday 11th June 2022, so keep these dates free and make a plan to attend ! Click this link to the WSR website to view the dates for other WSR events that are planned for 2022.
Class 52 D1010 ‘WESTERN CAMPAIGNER’ – we continue the steady drumbeat of progress on the bodywork of the locomotive, helped along by the flow of donations and the growing attendances at the depot, now open from Saturday through to Tuesday (most weeks). The old saying ‘many hands make light work’ is absolutely right. The following photographs tell the story:

D1010 – the door frame had to be curved to match the profile of the side of the locomotive, so Colin F applied gentle force to create just the right amount of curve to ensure a good fit. Pictured at Williton on Saturday 29th January 2022 by Andy Royal © CC BY-NC 3.0
D1010 – the replacement door frame has now been fitted neatly into place and is ready for welding. Pictured at Williton on Saturday 29th January 2022 by Andy Royal © CC BY-NC 3.0
D1010 – the tedious process of removing the many layers of paint and filler continues along the side of the locomotive that carries the scars of a previous repair to damage that was incurred some time in 1972.

D1010 – the needle-gunned surface is too rough to be painted, so it first has to be sanded down. The handrails prevent the use of power tools, so Ian F uses sandpaper to make sure that the area behind the handrail does not get missed.

D1010 – to prevent a layer of rust forming on the newly-repaired bodywork, Roy applies a thin layer of primer as a temporary measure, in advance of the sanding, filling and priming that will need to be done as part of the locomotive repaint.

Class 33 D6575 (33 057) – currently the duty loco, stationed at Bishops Lydeard (under cover, in Westridge Shed).
Class 35 ‘Hymek’ D7017 – Neil continued his work on the fitting of additional fuse protection into the electrical feed for the compressor and exhausters, which is a modification that has already been applied to sister loco D7018. This loco is waiting for its turn over the pit in the Swindon Shed so that her bogie suspension springs can be replaced.
Class 35 ‘Hymek’ D7018 – work resumed on the preparation for the removal of the transmission control block, which is a necessary step in the search for the issue that is preventing the automatic gear change from functioning properly. In the worst case, this loco will be ready for the DIESEL GALA from 9th to 11th JUNE and will operate while locked in second gear, as she did in 2021, but we hope that we will resolve the issue in time to allow normal operation.
Class 14 ‘Teddy Bear’ D9518 – another successful week with many more parts refitted to the loco frames, including some large pieces that have been taking up a lot of space in the loco shed while waiting their turn for re-attachment. This last weekend saw the re-fitting of the two sets of sandboxes and steps at the leading (longest) end of the locomotive, and the buffer beam received two coats of paint, first the primer and then the undercoat, which will be lightly sanded before applying further coats next week. Also, quietly and out of sight, John continued his work on the rebuilding of the electrical cubicle. Great progress indeed !

Class 14 ‘Teddy Bear’ D9526 – this loco is currently based at the Kent & East Sussex Railway and will remain at the K&ESR until May 2022, by which time her older sister D9504 should have completed her heavy overhaul and be returned to traffic. We look forward to seeing D9526 back at Williton in time for the WSR’s 2022 Diesel Gala that takes place from Thursday 9th through Saturday 11th June 2022.
Andrew Barclay 0-4-0DH 578 – this loco is currently in the Swindon Shed at Williton receiving attention from the WSR Restorations team who are performing a partial repaint that will then allow the loco to be stabled in the yard for the rest of the winter.
If you can help by donating your time, then please JOIN US and come along to the depot for an introduction to what we do and how we do it. We currently have people on site from Saturday through to Tuesday and we can open on other days if we can be sure of getting at least two volunteers on site at all times, so there is plenty of scope. We have tasks of all types to suit most capabilities, both skilled and unskilled.
Many thanks to all of our volunteers who give up so much of their time to work on the cleaning, painting, maintaining, restoring, managing and fund raising for our fleet of heritage locomotives !
BOOK REVIEW – we will skip this feature this week, but we will be back soon with another book review by long-term DEPG member and regular contributor, Neale Long.
ON SHED – we feature another photo from the extensive collection of Devon-based photographer Barry Gay, this time with our very own D1010 ‘WESTERN CAMPAIGNER’ making a full power restart from Newton Abbot station with the 1B91 0730 Bristol Temple Meads to Plymouth on Sunday 26th May 1974. The station looks sad, just a shadow of its former self, after being stripped of platform furniture some years previously. The clouds of black sooty ‘clag’ emanating from the loco are caused by ‘turbo lag’ which in turn is caused by the rapid increase in engine speed before the turbochargers have had a chance to catch up, thereby making the fuel-air mixture too rich, with dirty exhausts as a result. The exhaust will soon clean up as the engines stabilise. The German designers of the engines and transmissions were horrified by the harsh driving style demonstrated by some of the BR crews. Today’s engines are electronically controlled so that fuel flow is increased in unison with the increasing flow of air, regardless of the style of the driver.

Many thanks to Barry for sharing his photos with us all !
DEPG NEWS – some essential infrastructure improvements have been in progress at Williton, including the upgrading of the handwashing facilities in the loco shed, thanks to Graham and Jon, and the installation of a safety tag system, thanks to Martin and Paul T. Some pictures of their efforts are included below:
The upgraded handwashing facilities at Williton were put to the test by Colin G on Saturday 29th January 2022, and he appears to be happy with the results ! Many thanks to Graham and Jon for their hard work over several weekends to implement this enhanced facility. Photo by Jon Tooke © CC BY-NC 3.0
The implementation of a safety tag system to complement the ‘NOT TO BE MOVED’ boards was progressed by Paul and Martin at Williton over the weekend of 29th January 2022 with the creation and installation of a control board for the individual tags that will be assigned to each volunteer. This safety system will warn others when work is taking place on or inside a locomotive. Photo by Graham Perry © CC BY-NC 3.0
