A NEW TROLLEY.

An Underground System That Promises Success. The Metropolitan Traction Company believes it. has found an underground trolley system of street car locomotion that can be operated successfully, and it will be put in use on the new line in Lenox avenue. The road is already built. The surface construction is exactly like a cable road, and most persons thought the motive power would be cable,' although the company officials said that electricity would be tested. The conduit through which the conductors will run is like the cable conduit on Broadway. On each side of it, at distances, qf thirty feet, are soapstone pillars thirteen and one-half inches high and eight inches square. No wire is to be used at all. In its place are four and one-half-inch iron channel bars running from pillar to pillar, and resting on insulators. The pillars rest in cast-iron pedestals, provided with sockets six inches deep and one inch larger In Inside diameter than the pillars. The space then left is filled with sulphur. There is a manhole at each, pillar, so that in case of any trouble it will be possible to make instant repairs without interfering with the street. On each side of the conduits and

outside of the pillars are five pipes running the entire length of the line, and In these the feed wires will be carried. The arrangements for the drainage of the conduits is believed to be perfect. The trolley itself which will be used on the car is a five-eighth-inch steel bar, provided at the lower end with outwardly pressing springs, which are secured to positive and negative contact shores. The trolleys are attached to the car by crossbars attached to the side frames of the wheel trucks.—Electrical Review.
