This avoids a reboundof the selective switch andkeeps the flow of currentvery small through the mag-net. Accessibility of allparts has received considera-tion. Any part of the signalcan be removed without dis-turbing any other, and allwires entering the signal arefused and are in a separate box. The magnet coils are wound to perform their func-tion with a line potential as low as 300 volts. The sig-nal containing the operating mechanism weighs about50 lb. and the other 30 lb. They are attached to the polewith L-shaped brackets as shown in Fig. 2, and can beadjusted to allow for the rake in the FIG. 2—NEW 500-VOLTSIGNAL MADE BYDENVER TRAMWAY Women Substation Operators at Cleveland For some time past the Cleveland (Ohio) Railwayhas been employing women in substation operation withentire success. At present twelve are engaged in thiswork out of a total of twenty-four operators. The ex-perience of the company has shown that women havecertain qualities which are particularly essential in thiswork. They have a keen sense of responsibility andare very reliable in the performance of their are somewhat slower in switching operations,partly due to this conscientiousness and partly to inex-perience. For example, when there is trouble which byrapid switching might be taken care of, the womenare apt to let an entire station go out before startingup again. A skillful man might be able, in such a case,to get the equipment back onto the source of powerwithout losing the momentum of the station and thusinsure minimum loss of direct current power sup
