An interesting photo at Stratford with N7 0-6-2T 69714 on the coaling road, note the new diesel depot to the left and the rotating coal tipper on the right with another load of coal about to be emptied onto the conveyor (visible above the 3rd loco) which will carry it to the coaling stage and waiting locomotives, 12//7/61. ©Paul Tusan/Railphotoprints.uk
