Point heating:

Point heating keeps railway points free of snow and ice. Heatpoint uses different heating methods, depending on prevailing weather conditions and existing infrastructure. These include gas heating (infrared radiation), electric heating (resistance strip elements) and liquid heating (using a CH boiler or ground heat).

All these systems are energy-saving and have reasonable life-cycle costs, partly because they are operated by a microprocessor, weather station and a computer with user-friendly software.
