Following a successful trial by Network Rail, TDM’s GSM-R Trackside Telephone has been approved for use on railway infrastructure for which Network Rail is the Infrastructure Manager.
Network Rail has certified that the TDM GSM and GSM-R vandal and weather-resistant telephone is accepted for use at user-worked crossings and other similar locations where there are currently no fixed-line infrastructure, or where cost savings can be made in removing the fixed line infrastructure.
TDM’s GSM-R telephone is a stand alone unit: post-mounted and solar powered it is ideal for installation in remote environments. Using GSM-R and GSM technology, no cabling is needed, and diagnostics and configuration updates can be made via text message. Additionally, with dual SIM capacity the TDM telephone can have a secondary network SIM installed as a back-up should there be a network failure.
