The locomotive is built up of steel in the usual way, theunder frame being of the same kind as for an ordinaryfreight car. It is provided with a hand brake, as well aswith an air brake, the air pressure being produced by anelectric motor compressor. On the roof of the cab there are three vertical spindles,each carrying a current collector having a vertical alu-minum bow, which is pressed against the line wires by. FRONT OF CAR, SHOWING CONTROLLER, WANNSEE RAILWAY means of springs. Aluminum is used so as to lessen theirmass, and so assist the springs to keep a good bows are operated by the driver through gearing anda jaw clutch. Qn the roof there are also .mounted threeSiemens horn-shaped lightning arresters. The motors are operated at 750 volts, and in order tolower the pressure down from 10,000 volts, two transform-ers are provided. The high-tension switches are of Sie-mens & Halske special tube form, and are arranged in theroof of the car, the opening at the two breaking points,when switched off, being about a foot. As the switchcarries 10,000 volts, the actual operation of switching onand off is arranged pneumatically. If the condition of thetrack and its length would allow of it, the locomotive couldeasily attain a speed of 120 km per hour, and under suchconditions 2000 volts would be required at the motor ter-minals, when the winding is connected,
