Further to a previous news item posted on 29th November, following a committee meeting today and a review of the maintenance plan it has been decided that 37215 will now remain out of traffic until April 2017 . This means it will now NOT be appearing at the Christmas Cracker event on 29th/30th December.
Following fitting of its new pre-heater and subject to the fitting of new windscreen seals D6948 is planned to work on both days subject to the usual caveats on availability on the day.
Given that D6948 has now been fitted with a steam generator (for the first time in its history), the owners have taken the decision to fit an on-board pre-heater to allow heating of the engine block and cooling system prior to starting the locomotive when the temperature is cold. English Electric engines are notoriously difficult to start in cold weather, and whilst the effect is spectacular, it causes substantial engine wear and problems down the line. Put simply, every cold start takes hours of the life of the power unit. Given steam heat capability will increase the likelihood of the loco being started in cold conditions, pre-heating the engine was therefore considered essential for the well being of the power unit.
The pictures below, show the 9kW three phase electric preheater successfully fitted in the loco and plumbed in to the coolant circuit, meaning the loco can now be ‘plugged in’ to a 415v shore supply several hours before start up and brought up to temperature ensuring nice clean start up.

37215 has now been stopped for some much needed maintenance after a reliable season working all its diagrammed trains on the GWR without fuss, whilst the attention has been on its shiny new sibling D6948. The loco will remain out of service until April to enable a list of jobs to be carried out.
D6948, as might be imagined, has list of ‘snagging’ jobs to be done following its successful return to service, of which 3 are high priority: Resealing the window rubbers to prevent water ingress, installation of a pre-heater to avoid cold starts, and some work on the steam generator to cure its smoky exhaust and improve combustion and performance. Subject to some or all of these being done and with the usual caveat of ‘subject to availability’, the loco should take part in the GWR’s annual Christmas Cracker mixed traction event on the 28th and 29th December, which will see three diesel and 2 steam locos in action on each day.
