Current for the lights, compressor motor andcontrol is obtained from the secondary of an auxiliary trans-former which is wound to give 300 volts. Seven contactors are required for each pair of motors, andthe control is divided into five steps.

The Board of Trade fixed 20 volts as themaximum permissible drop in the return circuit, and this re-quirement made it necessary to install two-conductor boosterand distributer cables throughout the electric zone. The over-head line is sectionalized at each signal cabin, and series boostertransformers, with a ratio of 1:1, are located at every cabin.One side of these boosters is connected across the sectionbreak and the other is in series on the outer conductor of the

The taps from the sec-ondary of the main transformer give four voltages varyingfrom 450 volts to 750 volts, and the exciter transformer hastwo ratios. Combinations of these give five speeds, forward orreverse. Special precautions have been taken to prevent acciden-tal contact with any of the high-tension apparatus on the cars.All of the high-tension apparatus, with the exception of themain transformers, is mounted in cabinet built in the motor-mans compartment.
