Cab Secure Radio (CSR)

Cab Secure Radio

The Cab Secure Radio (CSR) is a Train-to-Signalbox analogue communication system which Siemens developed and supplied to the UK rail industry for the last 25 years prior railways migrating to GSM-R digital technology.

With the ongoing implementation of the new European standard GSM-R communication system in the UK, significant CSR opportunities still exist, and our test area is maintained for those projects.
