Abstract: A portable trip cock tripper for use with a train having a trip cock mounted thereon, such trip cock tripper being manually positionable in desired locations adjacent to a track rail and remotely operated for movement of its tripper arm from a trip cock engaging position to a non-trip cock contacting position.

Abstract: A train detector having dual ultrasonic sensors positioned adjacent to a rail for sensing the movement thereby of a train wheel and determining the direction and speed of the train for transmitting such information to nearby workers and signal devices and a method of train detecting are disclosed.

Abstract: A system for use by a railroad to warn railroad workers, track walker, railroad personnel and others of oncoming train(s) and to warn the train operator(s) of such train(s) of the presence of railroad workers, track walker railroad personnel, other train(s) and others on or near the railroad tracks, such system including at least one train transceiver for each train for sensing signals transmitted by at least one of a plurality of personal transmitter/receivers, one personal transmitter/receiver being worn by each of such railroad workers, track walker and railroad personnel, such train transceiver(s) to warn the train operator(s) of the presence of railroad workers, track walker, other train(s), and railroad personnel on or near the tracks when receiving signals from the personal transmitter/receivers, such personal transmitter/receivers receiving signals from the train transceiver(s) to warn the railroad workers, track walker and railroad personnel of oncoming train(s) with such warning signal activating ne

Abstract: A voltage testing apparatus for electrical railways is disclosed consisting in one embodiment of a transportable pole-mounted electrical power indicator, electrically conducting wire-engaging means such as a hook attached to one end of the pole and electrically connected to the indicator, and a ground-connecting device such as an electrically conducting magnet also electrically connected to the indicator. An electrical circuit is completed between the cable, the indicator and the rail by placing the hook on an overhead railway cable and attaching the magnet to a roadbed rail. An LED array and voltmeter configuration constituting the indicator illuminate and show whether voltage is present.
