Each half unit is complete in itself and is identicalin equipment with the other. The two units are coupledtogether at the cab-ends. The weight of the two complete half units is 136 metrictons (or tons of 2000 lb.) divided 18 metric tons on. P. L. M. Locomotive—Plan of Motor, Showing Methodof Gearing to Axle. (All Dimensions Arein Millimeters.) each driving axle and 16 tons on each bogie truck axle. Each driving axle is driven by a 300-volt, direct-current,six-pole, series motor having a i-hour rating of 400 hp ata speed of 650 , corresponding to a speed of the loco-motive of about 63 km (40 miles) per hour. The two motorsof each half-unit are connected in series. The armaturesof these motors are not mounted parallel to the driving axlebut are at right angles thereto and are connected to thedriving axles by bevel gears as shown in one of the draw-
