Point heating

Measuring the outdoor and rail temperatures with JUMO temperature probes

Cold outdoor temperatures as well as snowfall can cause the individual elements of the railway switches to freeze together if the railway switches are not heated.

In cold weather, heating comes into play to clear the ice and snow from betwen the switchrails ad the stock rails or the movable point frog. They allow the railway switches to continue to operate, thus preventing disruptions to the service.

 

Modern electrical railway switch heating design types are now fully automated. To do this, the system control unit needs reliable data about the local climatic conditions in the railway switch environment. Temperature sensors from JUMO provide measured values for the ambient and rail temperatures to ensure optimum control of the timing for switching the heating on and off.
