Graham Farish 371-986A GWR 64XX Pannier Tank 6422 BR Black (Early Emblem).
The Great Western Railway (GWR) 6400 Class is a class of 0-6-0 pannier tank steam locomotive introduced by Charles Collett in 1932. All 40 examples were 'auto-fitted', that is they were equipped with the remote-control equipment needed for working autotrains.
The smaller wheels of the 64xxs permitted operation in hillier locations than the 5400 Class and allocations were initially to the South Wales valleys.
Engines of class 6400 worked on many of the ex-GWR branch lines in Devon and Cornwall until the early 1960s, when the lines closed or diesel multiple units took over services. Number 6430 was a regular engine on the old Tavistock South branch line and would often run with two autocoaches. No. 6412 was based at Gloucester loco shed and operated the last 'Chalford Shuttle' autotrain service between Gloucester and Chalford in 1962.
