This cableis strung the entire length of both the Excelsior Springsand St. Joseph divisions. It is tied to the insulators withNo. 6 B. & S. soft-drawn copper wire and is rope-splicedand soldered. This feeder was erected before the bracketarms were placed and, as shown in the accompanying cut,this feeder is placed on the track side of the pole. The trolley and messenger is sectioned at four pointts,. K. C, C. C. & St. J.—View of a Tangent Over an Over-head Highway Crossing one being on each division to insulate the 1200-volt railwaycurrent from the 600-volt current of the Union DepotBridge & Terminal Railway, one at the substation on theExcelsior Springs division and one at substation B onthe St. Joseph division. Westinghouse 1200-volt sectioninsulators are used. The feeder is tapped into the trolleyapproximately three times per mile. These taps are No. 0B. & S. copper wire, soldered to the feeder and run throughtwo feed tap porcelain insulators and fastened to the feedtap trolley feeder. Rymco trolley switches are used at allturnouts. Garton-Daniels 1200-volt arresters are used for the pro-tection from lightning of the feeder and trolley arresters are located about five to the mile and areso spaced as to bring an arrester on each pole where afeed tap is located. These arresters are placed about 17 the top of the rail and are connected to th
