al castings. lem has 16 passenger cars, seating from 20 to 06 passengers each,and 67 freight cars of 12 to 15 tons capacity each. The type ofmotor car operated by this company is shown in ine of the illustra-tions. Current is collected from the overhead wires by two pairsof sliding bow trolleys mounted one pair at cither end of the car.This arrangement furnishes two rubbing contacts on each overheadwire, thus insuring freedom from interruption in any part of thecircuit. These trolley bows arc made as light as possible, so thatIhey will readily follow any irregularities in the overhead work. The power station of this system is at Candcr, where 16,000-volt.three-phase current is generated and distributed along the right ofway to transformer sub-stations. There arc 14 of these sub-stations,the general type of which is shown in one of the illustrations. Thetransformers in these sub-stations reduce the line pressure froml^).ooo to 750 volts, and their secondaries feed the two overhead con-

Theother part of the bracket, an arc of the same kind of pipe, is securedto the pole and the horizontal pipe by double sets of castings withset screws. The single round trolley wire is supported from thebracket arms by rigid hangers. Two different styles of guards for the trolley wire are shown,one in each illustration. Each is a simple metal frame, secured tothe bracket arm and carrying a number of protecting wires groundedon the frame work. In the illustration, which shows the intersectionof the electric track with steam track, the trolley pole constructionis of particular interest because of the high class of the workman-ship when compared with the methods used by American troUe;roads for supporting their wires at such critical points. It will benoticed that the wire is doubled and two sets of ears used on eachof the two brackets supporting the span over the intersecting tr
