Last weekend, Ian and Tom performed an ‘A’ exam on Class 33 ‘Crompton’ D6575 (33 057). The ‘A’ exam is a check-and inspect process that would have been performed once per week in the days when the loco was running on the mainline. For heritage railway usage, the check gets performed every 50 hours based on the engine run time. Because several days could pass before the loco is next put to use, the driver performs additional checks before starting up the engine and moving the loco.
D6575 required a top-up for the cooling system, so a quantity of pre-mixed water and anti-freeze solution was pumped in to make sure that the level was correct and to maintain the strength of the anti-freeze.
While on site at Williton, Ian performed a battery condition check on all of the locos in the DEPG fleet by measuring the voltage across the batteries and comparing against the standard value of 100 Volts. Here’s the results of the check:
|D1010||96V||Full day charge required (planned for 23-Feb-21)|
|D7017||92V||Full day charge given, now OK|
|D7018||100V||No action required|
|D9526||100V||No action required|
|47 077||96V||Half-day charge given, may need more (check on 23-Feb-21)|
If the batteries are allowed to remain discharged for long periods, they will lose their capacity to hold a charge, so it is important to keep an eye on these important parts to ensure that a loco can be started up whenever the need arises.
Many thanks to Ian and Tom for braving the cold weather to get this work done. The photo below shows the relatively luxurious surroundings that are provided to the batteries in ‘Hymek’ D7018:
WSR Operations Manager and DEPG member Paul Fleet will be attending at Williton during the coming week to run D6575 and he will also attend at Bishops Lydeard to run Class 09 shunter D4107 and our Class 33 ‘Crompton’ D6566 (33 048). The engines are run for long enough to maintain their battery levels at full strength without the need for separate charging, while checks are performed on the ancillary machines such as compressors, exhausters and blowers.
DEPG member Bob Clegg has organised a small team to check the Maybach engines that are installed in our ‘Hymeks’ and in our Class 52 ‘Western’ and to perform pre-heating and running of the engines where possible. This work is planned to take place on Tuesday 23rd February and such attention will keep these irreplaceable machines in good working order. Terry will also attend to run a check over Class 14 D9526.
Around half of our regular volunteers have now had their vaccinations, so there are continual signs that progress is being made. We can’t wait to get back to Williton and get on with the work!
This weekend is the 44th anniversary of the “WESTERN REQUIEM RELIEF” railtour that ran from Paddington to Aberdare, Merthyr and Treherbert at the heads of the valleys of South Wales with our very own D1010 ‘WESTERN CAMPAIGNER’ doing the heavy hauling. The railtour route was via Gloucester to Cardiff then to Pontypridd and onward to the very end of three of the valley lines, reversing at Pontypridd each time.
The “relief” ran a week before the main tour because of the very high demand for tickets, and both tours were a sell-out. This fantastic image of D1010 at the headshunt just beyond Treherbert, just over 1000 feet (302m) above sea level at the head of the Rhondda valley in South Wales, was captured by Kelvin Lumb on the day of the relief tour, and shows the admiration of the those who had travelled independently to this remote spot to pay homage to the Class. The loco was then uncoupled from the train and ran round the coaches to re-couple at the south end and haul the train back into Treherbert station. Many thanks to Kelv for sharing his photos with us.
This railtour, and others, will be covered in detail in our forthcoming booklet “D1010 – from Merehead to Minehead”.
WSR NEWS: The WSR have introduced a requirement for all competency records to be held electronically within HOPS. The Heritage Operations Processing System (HOPS) is an on-line facility that is used by many heritage railways to handle the complex business of staff (both paid and voluntary), operations, training, competency, rostering and a host of other useful things.
The DEPG is well prepared for this, due to work that has been done in the background by our Martin Howard and Simon Purvis, and it is great to see that the WSR is one of the leaders in the adoption of HOPS and will benefit from the ‘one system process’ that is now mandatory across the WSR family of organisations.
In practical terms, it means that our volunteers need to demonstrate competency and have records maintained to verify competency before performing any kind of work on our locomotives. This may sound like ‘a load of red tape’ and it will no doubt cause frustration to some, but considering that our locos are irreplaceable, these are the obligations of the DEPG trustees and we need to be able to demonstrate that our locos are being looked after in a professional way, in addition to being critical from the viewpoint of safety.
