GWR 7022 Hereford Castle at Severn Tunnel August 1951 by John Wiltshire
[Neg 100]
I love the framing of this image by John with the signals. Remarkably sharp for a 1950s camera with limited shutter speed.

Its shot on Ilford  Selochrome film 1/100th second at F8 so the loco could not be going very fast.
