The company has altogether 2S cars, 15 fitted withSprague motors, 13 with the Thomson-Houston, and 3 with theVan de Poele. On these lines the number of passengers car-ried averages about 175, 000 mont_hIy, and on special occasionsfrom 15, 000 to 20, 000 have been carried in a day. The ordinaryduty of a car is about 100 miles per day. The system in use isthe overhead wire, the power-wire being carried above the track Vol. LXIII, No. II.] ENGINEERING JOURNAL. 529 on brackets suspended from cross-wires stretched from poleson either side of the street. A feeder-wire is carried on thepoles on one side, so that in case of a break in the main wire, a new connection can be made at any point and current sup- boilers 16 ft. long and 6 ft. diameter. There are two furnacesto each boiler, and the fuel used is culm or coal dust, which issupplied from a huge pile at the back of the power-house. Thestation is. in fact, remarkably well situated for securing a cheap. plied without delay. The connection between the power-wireand the car is made by a trolley carried on a long iron rod ontop of the car, and the connection can be made or broken by aslight movement of the conductors or drivers hand. The carsrun very smoothly and well, and do not seem to experience anydifficulty in climbing the steepest grades. The power-house, from which power is supplied to the differ-ent lines, is very completely fitted up. There are three Arming-ton & Sims engines of 125 H. P. each, which are kept constantlyin service, and which run six No. 20 Edison dynamos, havinga total power of 600 ampires. A very trying feature in the supply .of fuel, being in the immediate neighborhood of one ofthe coal mines with which the region around Scranton abounds.This electric road may be considered in every way a success, and the accidents and delays are fewer in number than on anordinary horse railroad.
