Snow and ice build-up on track poses a major safety risk, and can cause serious disruptions to rail service. A well-performing switch point heating system must prevent the moving switch (point) blade from freezing, prevent the switch rail from freezing to the supporting slide plates, and prevent any buildup of snow, sleet or hail between the switch rail and the stock rail that could compact and prevent the point system from operating correctly.

nVent ERICO provides customized heating systems that melt snow and ice on railway switches, improving safety and reliability in the harshest winter conditions. The nVent ERICO Rail Heating System provides robust snow and ice melting performance via a self-regulating heating cable that automatically adjusts power output according to changes in temperature. This advanced heating cable technology is significantly more efficient than conventional heating elements, resulting in a lower cost of ownership over its life-cycle. Self-regulating switch heating systems have been in service for more than 20 years, and is suitable for all types of rail transport, including high-speed, conventional freight rail, metros, tramways, and light rail systems.
