D15 463 as rebuilt by Robert Urie at speed on a down West of England express.
The painting is by railway painter and author. Cuthbert (Chip) Hamilton Ellis FRSA (29 June 1909 – 29 June 1987) was an English railway writer and painter. He was an Associate of the Institution of Locomotive Engineers and a Fellow of the Royal Society of Arts.
His book 'The London and South Western Railway' was my first proper railway book and its influence is still strong.
