"This is how it works". Some salient feature of 7MT 4-6-2 70013 Oliver Cromwell is pointed out at Toddington on 2 June 2018, as the loco waits to leave with the 10:00 service to Cheltenham Racecourse. The loco had arrived at the Gloucestershire Warwickshire Railway for the previous weekend's Cotswold Festival of Steam.
