None of the cylinders of these engines is jacketed,but they are well covered with non-conducting material, andan exterior finish is made with planished sheet iron. The distribution of the steam in both cylinders is effectedby means of two balanced piston valves of the Tosi are placed on the same rod and operated by oneeccentric controlled by a shaft governor, which varies thecut-off from o to 50 per cent of the VIEW OF TRACK AT STATION, SHOWING COVERED THIRD RAIL The frame is of the double-branched or A shape, casttogether in one piece with the two bearings. The guides onthis class of engines are bored. The hub of the fly-wheel isshaped into a small pulley to drive by belt the horizontal Tosi works, and are of the water-tube type. Each boiler has312 sq. ft. (290 sqm.) heating surface, and sq. ft. ((sqm.) grate surface. Each boiler has 144 tubes, 17 ft. \
