GWR Star class 4-6-0 No 4018 Knight of the Grand Cross waiting outside Paddington before backing down on to its train in August 1931.

Peter Kerslake says" 4018 waits on the approach to Paddington, ready to run back into the station and on to the stock awaiting its next duty, the 3500 gallon tender well filled with coal prior to coming off Old Oak Common."
