e-WARM is designed to prevent problems in the railway switches, which occur due to snow and icing at adverse weather conditions. The system enables automatic operation with the help of its snow-ice and temperature sensors and ensures uninterrupted and safe railway operation.

Technical Specification

Thanks to the redundant communication architecture and weather stations the system has low power consumption and high reliability.
Communication between control unit and site is achieved through ﬁber optic cable, which eliminates excessive costs for using copper cables.
Communication through ﬁber optic cables provides eﬀective transmission of higher quantities of operation and maintenance indications of the switch heater to the interlocking unit.
Each switch heater is controlled separately. Status indications of all equipment on the system (Fuses, switching devices, PLC’s, etc) are sent to the control center. Thus, the time to remedy any failure in the system is kept at minimum.
The system can be applied to switches at all locations and all rail systems, from high speed train lines to maintenance/marchalling yards, main line railways, commuter lines, metros, light rail and tram systems.
Industrial processors are used on the site cabinets and central units. Therefore, any of communication solution like Modbus TCP, dry contact and serial port can be used for interlocking and control center connections.
E-WARM saves time and cost, providing variable interface applications and easy installation feature.
