The Street railway journal . tober 8, 1904.] STREET RAILWAY JOURNAL. 5i3 rotary panels equipment is as follows: Circuit breaker, am-meter, rheostat operating mechanism, two double-throw quick-break main switches, auxiliary switch and a two-point plugreceptacle. Booster-motor panels contain circuit breaker, am-meter, starting switch, one single-pole double-throw mainswitch and auxiliary switch. The battery panel is equippedwith circuit breaker, ammeter, ten-point potential receptacle,two double-throw switches and auxiliary switch. The load the lower bus of 20,000-amp. capacity, at the points of maxi-mum cross section. If it is desired to put the battery on cer-tain feeder sections or one machine alone on certain sections,it can be done by simply using this upper bus. The oil switches,board signal lamps and relays are operated from 125-volt mainssupplied by a 55-cell auxiliary battery. The station was erected and designed by the engineering de-partments of the St. Louis Transit Company according to the. REPRESENTATIVE VIEW OF ST. LOUIS—OLIVE STREET LINE HANDLING WORLDS FAIR TRAFFIC ON TULY panels hold two astatic ammeters, two differential voltmeters,one 20,000-amp. wattmeter and one 10,000-amp. equipment consists of circuit breaker, ammeterand one single-pole double-throw quick-break main direct-current feeders leaving these panels are of roundcopper rods, I in. diameter, carried along the wall on specialbrackets to a terminal pole outside the building. The rod con-struction may be clearly seen in the photographs. The switchboard supports two positive busses of J4~in, x10-in, copper. The upper bus is of 10,000-amp. capacity, and plans of A. B. duPont, general manager of the company at thaitime. L. P. Crecelius, the companys electrical engineer, super-intended the designing ami construction of the station. The original plan of installing seven iooo-kw rotaries in theCentral sub-station has been changed. Six io
