The accompanying illustration (from Industncs) shows anelectric locomotive built by Immisch & Company, London,England, for the Wharncliff-Silkstone coal mine. It runs on aline of 2i-in. gauge, the mine tunnel being 4 ft. high by 4 ft. 6in. wide, and its total weight is tons. Fig i is an elevationand fig. 2 a plan of the engine.
