I have a nice colour pic of class 29 D6107 in ex works blue livery which states on the back that it was taken at Carlisle Kingmoor in August 1967. I cannot say for sure that it is Kingmoor, but it is certainly a steam depot.
Assuming that it is indeed Kingmoor, is it possible that D6107 wrked via the Waverley Route with a relief train from perhaps Dundee to Morecambe or Blackpool? The loco displays a 1Z headcode indicating a special or relief train?
I know that traction knowledge would have been an issue, but that would have been the same regardless of what way the train was routed. Anybody got any ideas?
