Kossoff had met Auerbach during his first year at St Martin's and, at Auerbach's suggestion, he attended David Bomberg's evening classes at Borough Polytechnic in South London, during 1950-2. Under Bomberg's tuterlage Kossoff developed greater confidence and freedom in his drawing technique and commented that, 'Coming to Bomberg's classes was like coming home' (see P. Moorhouse, op. cit, p. 12).
The present work depicts a train leaving Willesden Green Underground station in North London, which Kossoff would have executed from a bridge near his studio. It is very close in composition to his oil, From Willesden Green, Autumn, 1991 (private collection) and in both works a group of workman in orange jackets are visible, standing at the side of the track. This subject matter of a train leaving a station provided Kossoff with the opportunity to create a dynamic composition with strong diagonals and long sweeping strokes suggesting the speed with which the train is departing.
