A TROLLEY SWITCHING CAR. The West Chicago Street Railroad has recently put adinkey motor car at the ONiel street barns to do the switch-ing for the South Ilalstead street cable line. The car takesthe place of 13 horses and two men and does the work inshorter time and in a yery satisfactory manner. It requiresbut one man to operate the motor. Perhaps the trolleyarrangement is the most interesting feature of the car. Anordinary trolley would require another man and be entirelyunsuited to the wiring which is without switches. A home-. made contriyance was designed which has sohed the the end of a 2-inch yertical pipe a beam is piyoted. Onone end is a 5^-inch steel wire bent so that it is about 6 feetacross and this forms the contact to the trolley wire. Onthe other end of the beam is a weight which insures a con-stant pressure of the wire against the line. This makesallowance for the slack in the line, does not break contactwhen switching from one track to another and makes it pos-sible to use the crude system of over head wiring now inplace. The accompanying illustration represents trolleyarrangement. SALT WAR IN WASHINGTON, D. C.
