Token Instrument & Radio in one compact unit
The Cab Display Radio (CDR) combines the RETB VHF radio and token instrument into one compact unit, simplifying train installations.
The CDR allows the driver to receive and send track access tokens, which are clearly displayed on the unit.
Each CDR token unit is uniquely coded. The signaller issues a token to that unique ID which can only be decoded by the corresponding token unit. To receive a token the signaller requests, by voice call, that the driver presses the Receive button on the CDR. Only then can the token be decoded by the CDR. This combination of code and driver action ensures only that unit receives the token.
The CDR is part of the on-train installation, product approved by Network Rail in the UK.
