6809 1956 Par
Looks like a spot of re-marshalling may be going on. The second vehicle is a Cornish Riviera Expres Restaurant Car.
Peter Kerslake says "Penzance allocated 6809 "Burchclere Grange" is displaying express passenger lamps and with that stock I wonder whether it has taken over from here this part of the up Saturday "Cornish Riviera" which has been worked down to Par by a lighter engine from Newquay.
If so, then 6809 will work its train as far as the main line at Laira where a waiting fresh "King" or "Castl"e will take the train to Paddington, this working not calling at Plymouth North Road on Summer Saturdays in the mid 'fifties."
