Technical Committee (TC) Rail Telecommunications (RT)

We are responsible for the development and maintenance of standards related to GSM-R (GSM™ for railways) as well as Next Generation Radio for Rail (NG2R).

The international railway community has long used enhanced GSM™ technology to meet its operational needs. GSM-R is based on the GSM standard, with added features specific to the railway environment, including data and voice communications at commercial speeds of up to 350 km/h and beyond. GSM-R now reaches over 120 000 kilometres of railway lines in Europe and a further 120 000 kilometres throughout the rest of the world. Most Western European railways are now fully equipped with GSM-R on their high speed and conventional lines.
