A short line equipped with this system wasoperated successfully for several years on North Capital Street,Washington, and it has been in active daily service in the yardsof the Westinghouse Company for the past four years. The Government has recently installed an electric railway on. speed, requiring only a few seconds, switch B is closed; currentthen passes from transformer through wiring R R, contact shoeQ, pin No. r, coil H to ground. This current passing through thecoil H, magnetizes the core S, which, in turn, attracts the arma-ture P, closing the switch and establishing connection betweenthe pin 2, and the 500-volt main feeder K, K, through wiring N,coil I, and contacts; switch C is now closed and switches A and Bopened, the transformer then stops, the switch X2 is kept closed,however, by the current flowing from the main feeder throughlamp L connection R, M, coil H to ground. The car now pro-ceeds on its way, current from the main passing through coil I,contact bar A2 connection T, to the controller and motors in theusual manner.
