'Flying Scotsman' A3 Class steam locomotive leaving Leeds station, Yorkshire, with the 'White Rose' express for King's Cross station, London. Photograph by Bishop Eric Treacy.

He also befriended many of the footplate crews, occasionally persuading them to create special smoke effects for the camera.
