By the commonmethod of backing up the motor car to hitch to a trailerthe trolley has to be turned three times where once sufficeswith the plan under discussion. Then again, three over-head switches are necessary with the common methodand only one with this. In fact that single overheadswitch is not a necessity, as the motor car is alone andwill run through by momentum. The fact that the ropemethod eliminates the running over with current on of weight on it while it is being thrown and consequentlythere is little wear. For an electric road the most advantageous arrange-ment would probably be to put a run-off at A, a springtongue switch, held normally for the cross-over at B anda run-off at C.

The trailer switch at B is set by aspring for the crossover, so that the trainmen never haveto bother with throwing switches. At C is a springpoint switch which is held normally in position for themain line. As the trailers come onto the main line fromthe cross-over they open this switch against the springbut as the point is on the inside of the curve there is no JAPANESE ELECTRICAL PAPER.
