| Additional Notes | P pre 1977 as Support Coach for "Blue Peter". Dinting till 1986, then to ICI Wilton. 1992 to Llangollen. Part of one side had rotted and fallen off, with part of the remaining frame also rotten. Restoration well advanced by 07/12, by which time all the frame repairs had been completed, body reclad in new steel, and in undercoat for a BR crimson lake and cream livery finish. All compartments had been removed in Departmental days: not planned to reinstate these. Instead, planned to restore the passenger half as an open saloon with First Class style seating to accompany Buffet Lounge car 1706. The double doors at the Brake end will provide disabled access. All this will not change the external appearance (see main photo and second additional photo) and will not prevent any future restoration back into a BTK. By 08/18: moved to North Norfolk Railway where, 08/19, restoration work is continuing.
