All of the four sub-stations, which step down the voltagefrom 6600 to 600, work in parallel on the system, consequentlythe stations do not form separate feeder sections, which would have required more stations than the parallel method. Thestandard size transformer adopted is 75 KVA, of which theHorny station contains one, Wasmes two, Frameries three andQuaregnon two. All of the stations are built of masonry, ap-proximately 10 ft. 6 ins. x 7 ft. 10 ins. in area, and containthe necessary controlling apparatus in addition to the trans-formers. The entering high-tension wires are first led to apair of hand switches and then through an oil switch to theprimary bus-bars, whence they pass to the transformers. In. DOUBLE-POLE MOTOR RAILWAY CONTROLLER FOR SWITCH SINGLE-PHASE SERVICE each station wattmeters are placed at the entering side, so thatthe exact energy used, including transformer losses, is easilydetermined. THE RAILWAY LINEAlthough one overhead wire is sufficient in single-phase op-eration, the company uses an additional wire for the return
