"From this place of manufacture, so to speak, the current is distributed to four other substations scattered over the city, known respectively as the Plaza, University, Westlake and South Park substations. In these there are no oil furnaces, boilers, or steam engines; only the electric current itself has to be dealt with, so that there is economy on the score both of plant and of labor. The central station, besides generating the electricity, also performs the work of a substation. It sends out about 40 per cent of the power used for the operation of the street cars on the Los Angeles Railway Company's system. The Plaza station, distributes the next 40 per cent used, while the three others combined account for the remaining 20 per cent."
