Layout of 1200-Volt Locomotive is mounted in a grounded expanded metal cage whichprotects the apparatus and yet allows it to be accessiblefor maintenance and inspection. It will be noted that the reversers or series parallelswitches are placed next to the floor, the switch groupsand line switches directly over them, and the resistorsdirectly over the switch groups under the roof. Thegrid resistors are mounted in the main cab over thtswitch groups and are enclosed in a steel cabinet openat the bottom and provided with hinged doors on eachside so as to secure easy access. Ventilators are pro-vided in the roof over the resistance cabinet. Forcedventilation is supplied by blowers mounted on the ex-tended shaft of the dynamotors. The air-brake dis-tributing valve is conveniently located inside the cabwhere it will be kept sufficiently warm to preventfreezing. The control apparatus of each locomotive consists ingeneral of the following: Two master controllers, twoswitch groups, two cha
