Exterior of the station building. sion system is extended on south to a ter-minal substation in the general vicinity ofNewark. Such a voltage requires a wide separa-tion between the wires comprising the threephases, and, consequently, a large stationarea is essential to accommodate the lineswitching equipment. The incoming lines from Vaca supply abank of three 10,000 K. V. A. transformers,with a fourth transformer held in reserveas a spare, and the voltage is reduced to60,000 and 11,000.
