ELECTRICAL DANGERS IN THE SUBWAY.
Interborough officials say that fire danger in subway cars from misplaced electricity or other cause is, to all practical intents, impossible. On the Third avenue Manhattan Elevated road, at One Hundred and Twelfth street, lately, fire due to an overturned car and the resulting displaced electrical discharges almost consumed the ties and elevated structure alike. The subway motor cars are of tempered steel and are fireproof. While the “trailers” have no electrical connection, even they are coppersheathed. The floors of both motor cars and “trailers” are built of fireproof transite. Again, on the elevated, to shut off power on a rail, it is necessary to search for a telephone and then come into com munication with a sub-station. In the subway it is simply necessary to turn the handle of one of the small alarm boxes that are scattered throughout the tunnel at distances of some four hundred feet, to shut off the power automatically. Then, too, the third rail is well protected.
