Tucked away out of sight inside the loco shed at Williton, work is proceeding on the exhaust system overhaul of Class 33 ‘Crompton’ D6575 (33 057) to get her ready for a return to service before the end of March. This time of year, the demand for the occasional engineering train is easily met by sister Class 33 D6566 (33 048) or by Class 14 ‘Teddy Bear’ D9526, both locos being available for use by the WSR at any time, but this will change when the line reopens in March, with the need to support operations and the need to run special services for refreshing the train crews.
Progress on D6575 has been held up by having to wait for the exhaust gaskets to be delivered. The first batch were incorrect and the second batch were rejected by the manufacturer before shipment, so the third batch ought to be right !
The photo below shows that the roof of the loco has been lifted off to allow easier access to the large and heavy exhaust system components, most of which have now been removed from the loco for clean up and inspection. The Sulzer 8-cylinder diesel engine has been checked over and one of the cylinder heads was found to have worn valve guides, which reduces efficiency and increases oil consumption. This issue has been caught at an early stage and the cylinder head replaced with a known good spare from DEPG stock. Other cleanup work will continue while we wait for the gaskets, then we will need a few weeks to put everything back together and perform the necessary checks and inspections before the loco returns to service.

LOCO NEWS:
Class 52 D1010 ‘WESTERN CAMPAIGNER’ – the focus for the team at the moment is the planning of the lifting operation that will allow the bogies to be rolled out so that they can be overhauled. The plan is for the loco be lifted by two 100-ton road cranes working in tandem, that will be able to slew the loco body aside so that the bogies can be moved out of the way and the stands placed in position instead. The loco body would then be slewed back into position and lowered onto the stands.
The stands themselves are massive steel fabrications, each weighing more than 1 tonne and dating back to the 1960s. They were used at Swindon Works until made redundant by the withdrawal of the Class 52s. As the picture below shows, they are in need of a clean up, after which they will be inspected to ensure integrity then given a fresh coat of paint. That’s another job that needs to be done ASAP !
Meanwhile, the transmission team have made very good progress and have re-fitted the top cover to the overhauled ‘A’ transmission. It is not photogenic because it has yet to be painted, but it has now been overhauled and only needs the rest of the peripherals reattached to become a complete working unit once again. WELL DONE TEAM !
The restoration of D1010 is a major project and we will need MORE HANDS to help us get the work done. If you want to see this locomotive back on the rails soon, then PLEASE COME ALONG AND HELP US WITH THE WORK ! There is plenty more to do, so simply reply to this email or use the CONTACT FORM on our website if you can lend a hand.

Details of the work remaining to be done on this restoration project along with a status report of the funding have been included in the new issue of the DEPG Newsletter, which has now been distributed to DEPG members. A summary will be posted via roundup soon, but JOIN THE DEPG to get the information in more detail and more quickly.

See our CAMPAIGN for CAMPAIGNER web page for more details. We still have a lot of work to do on this massive locomotive, so PLEASE DO COME ALONG AND HELP IF YOU CAN !
Class 33 D6566 (33 048) – this loco is currently based at Williton and is available for duty.
Class 33 D6575 (33 057) – as outlined earlier, the replacement cylinder head for number 5 cylinder has now been installed, so the team can now return their focus to the exhaust system.We hope to have this loco back in service some time in March.

Class 35 ‘Hymek’ D7017 – as reported last week, this loco is ready to return to service subject to some test runs that will be used to accumulate hours and ensure reliability. This loco will undergo an oil change when warmer weather returns and will be ready for test running as soon as the WSR re-opens.
Class 35 ‘Hymek’ D7018 – the temporary pressure gauges that were being used to monitor the control pressures have been reorganised and relocated to make them easier to read. This also makes them easier to film, the video evidence of the pressures at startup being essential information in the fault-finding process. The next step is to check that the six control pistons are correctly set and can achieve full and free travel. These checks will ensure that the maximum amount of useful information is obtained from the next engine startup.
Class 14 ‘Teddy Bear’ D9518 – the team continued their preparations for the electrical re-wiring and the installation of the cab by completing the restoration of several more electrical junction box enclosures along with the associated specially-shaped trunking. In parallel, work continued on the cardan shaft replacement activities and on the compressed air pipework for the windscreen wipers.
Details of the work remaining to be done on this restoration project along with a status report of the funding have been included in the new issue of the DEPG Newsletter, which has now been distributed to DEPG members.

This loco is the subject of a fundraising appeal so please follow this link to find out more. We need your help ! In addition to funds, we also need plenty of HANDS. If you love the ‘Teddy Bears’ and you are not already a member of the DEPG, please join us so that you can become one of the team that is going to return D9518 to fully operational condition as ‘NCB No. 7‘.
Class 14 ‘Teddy Bear’ D9526 – this loco is on standby at Bishops Lydeard for use on engineering trains.
Class 47 47077 ‘NORTH STAR’ – after receiving a top-end overhaul at Grosmont Works, this loco is now ready to take up duties on the North Yorkshire Moors Railway. The plan is for this loco to be in use later this month.
Andrew Barclay 0-4-0DH 578 – this loco is stabled on number 3 road at Williton and is ready for use if required.
If you can help by donating your time to any of these projects, 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 !
