A surface conditioning device for railway track rails and/or railway vehicle wheels includes a DC power supply, a supply of gas, a plasma delivery head connected to receive DC power from the power supply and gas from the gas supply, and an igniter for igniting the gas in the plasma delivery head. In use, plasma is generated within the delivery head by ignition of the gas in the delivery head. Plasma with gas is blown from the delivery head onto a railway track rail and/or railway vehicle wheel, thereby conditioning the rail and/or wheel.

The present invention relates to heating device for melting snow and ice from a railway track, wherein the heating device comprises a connection plate (3), a heat element (5) attached to the connection plate, and at least one securing member (7) for securing the connection plate to the track. The securing member (7) is configured to clamp a part of the track between the securing member (7) and the connection plate. An outer portion (8) of the connection plate (3) is bent inwards so that a hook (11) is formed at an end (4a) of the connection plate for receiving a part of the track, and the hook is provided with at least one through hole (16) for receiving the at least one securing member.

A system for remotely controlling third rail ribbon heaters is provided for preventing the accumulation of ice and snow on the rails. The system includes a plurality of switching assemblies that control a flow of electric current from the third rail of a railway to ribbon heaters mounted on the third rail. A remotely located digital controller provides switching commands to the switching assemblies via a radio link. The switching assemblies include current and voltage sensors that continuously provide current and voltage information that allows the digital controller to accurately predict when a heater failure condition is likely to occur so that ribbon heaters may be preemptively and safely replaced before failure. Each of the switching assemblies is contained in a junction box that includes both a door panel and a safety switch that disconnects the switching assembly from third rail current when the door panel is opened for improved safety.
