Early Railroad Experience
The first Thermal-Flex Switch Heating System was installed in 1976 on a 30 foot spring switch for the main line of the Central Vermont Railway at White River Junction, Vermont. This early design was later improved upon with the addition of two crib heaters in the switch rod area.
Further product development and system enhancements have resulted in the switch heating systems we offer today. Thermal-Flex products are in use throughout North America and Europe under a diverse range of climatic and operating conditions.
