A device that attaches to a pneumatic tired convertible rail highway vehicle for the purpose of shunting electrical current of railroad tracks so that the current will actuate signaling devices. The shunt mechanism is actuated by raising and lowering the guide. No other actuation is needed. The shunt mechanism is located between the road wheel and the rail wheel. A wire or carbon brush makes electrical contact and closely follows the guide wheel. The shunt mechanism is mounted on shafts allowing adjustment for the gauge of the track. A reinforcing bar prevents radial twisting of the carbon or wire brush. A spring provides a light constant tension against the carbon or wire brush to insure electrical contact.
