On July 4 1958, a 4-EPB unit passed a signal at danger and ran head-on into a steam locomotive at Maze Hill. The loco, Wainright 'C' class (BR no. 31461), had run round a rake of empty coaching stock which it was going to take to Herne Hill sorting sidings departing (I think?) in the Down direction. The loco rode up over the underframe of the leading coach of the EMU and demolished the cab and brake compartment, and penetrated the passenger saloon. Amazingly, the motorman was hardly hurt and was found sitting on the bogie frame. What I have been wondering is the route the empty stock train was going to take. I wonder if it was Slade Green, Bexleyheath, Lewisham, Nunhead, Denmark Hill, Cambria Spur to north of Loughborough Junction, where (maybe) it halted and another loco took the carriages into the sidings?
