Class 104 DMU at Stalybridge

May 1984

Set number: EXPDM352

Experimental DMU no. EXP DM 352, consisting of cars 78601 (nearest, formerly 50521) and 78851 (formerly 50446) both of which had had one of their two 150hp engines removed as a proposed cost saving measure, seen at Stalybridge in May 1984. It is said that the unit was underpowered - although it should have had the same power as a 'conventional' Class 101-109 power-trailer or 4-car unit - and the only other cars to have this modification carried out subsequently were the Metropolitan-Cammell Class 111s, which had 180hp Rolls-Royce engines. This unit was one of the few Class 104s to receive blue & grey livery, plus the black strip below the cab windows was presumably to mark it out as non-standard. Graeme Phillips Collection.
