For me a most evocative shot of the transitional steam to diesel era. One the last classes of steam locos to remain in traffic were the Stanier 8Fs, introduced in 1935 and which remained in traffic until the very end of main line steam in August 1968.
48036 has 8E (Northwich) chalked on its smoke box door; there appears to be signs of overhead electrical warning flashes and the general rundown nature of the depot suggests a date towards the end of steam.
Is the 8F at its home shed, if not where?
