Transformers are placed in niches at suitable points to bothtunnels and the primaries are fed by 440-volt feeders from thesubstation, whle the 104-volt secondary side of the transformersis fed directly to the lamps. There is a lighting cabinetin each transformer niche to control the lighting in its im-mediate vicinity, and each cabinet controls eight local light-ing circuits and in some cases signal track transfoimers have aprimary feed from the lighting cabinets. These transformersare single phase, of 7^-kw capacity, and are connected alter-nately to the different legs of the three-phase feeders in such,a manner as to balance the load. The lighting of the yards is accomplished by 100 7^-amp_.
