Any coaching stock in blue,/grey.However, Deltics were never suitable for freight trains (though they once appeared on a freightliner). MkIII coaches (loco hauled type) could in theory be used with a Deltic but were never used as the electric train supply could create havoc with the workings of the buffet.
I spent a lot of time photographing Deltics in their latter years and whilst they certainly were relegated to T-P workings, I never recall seeing them on anything other than passenger turns including sleepers, but no parcels workings.
That doesn't mean to say they didn't get used for such jobs, but I'd be interested to see any proof to back-up your suggestion.
I'm trying to find out whether SC12014 & SC11007 were actually part of a Edinburgh-Glasgow push/pull set. If they were they would not have been in that use for long as Mk3s were only introduced on those services in 1979.
Prior to the introduction of Mk3s the services were top & tailed by class
Unfortunately the oldest P5 Coaching Stock book I have only dates back to Spring 1987, but sheds some light on the coaches' careers:
TSO 12004, built Derby 1975 - by 1987 it was assigned to Edinburgh Craigentinny (EC), wearing Scotrail livery, so it would have been in a push-pull set. FO 11007, built Derby 1975 - by 1987 it had become CO 11907, and was based at EC in Scotrail livery - the COs were only used in push-pull sets.
John, the Sc prefixes on the coaches in your photo are a tell-tale sign that they certainly were push-pull stock, else they would have had M prefixes (WCML stock being based at Willesden Brent Sidings, Longsight, Carlisle Upperby and Liverpool Downhills in the 70s). The Deltic was possibly hauling them from Derby to EC after mods?
Yes, it's been confirmed that both were used in push/pull sets in the early
1980s (presumably being converted & in such use in 1979) when the class 27s & Mk2s were replaced by 47/7s and Mk3s.
Unfortunately I've no real memory of taking this image, and consequently cannot confirm whether there was a DBSO at the other end of the rake. I suppose it could have been a special to Yorks races, or even one of the wakes trains which had worked through to Scarborough, although it appears to be enteringYork station from the south.
This may give credence to your suggestion of a visit to Derby Works, but although *smart* the coaches do not appear to be in *ex-works* condition.
