A railway vehicle safety shunt system includes a pair of axle-mounted rail wheels having outer circumferential surfaces that engage the upper surfaces of the rails, respectively, radially outwardly flange portions that engage the lateral portions of the rails, respectively, and adjacent end surfaces that are respectively engaged by a pair of spring-biased wire brushes arranged parallel with the axis of rotation of the associated rail wheel. The brushes are electrically connected by a shunt conductor, thereby to present an indication of the location of the railway vehicle at a remote vehicle position monitoring and dispatching station.
