GSM-R user procedures (cab radio Version 2)

Once the Lead Driver ends the call to the signaller, the cab radio will automatically retrieve

the held call (Driver 2) and the two drivers can then use the GSM-R system to

communicate.

 The cab radio allows the receiving party to replace the handset on its cradle and

operate in ‘hands-free mode’. So, if assistance to a failed train movement is

authorised, then, for example; the driver in control of power and brake at the rear can

receive instructions over the loudspeaker from the driver controlling the train

movement at the front. However, the behaviour is different for the call initiator as

replacing the handset onto the cradle will terminate the call.

 If the GSM-R system is being used to control the movement of a train and during the

movement communication is lost or interrupted, for any reason, then the driver in

control of the train brake must immediately stop the movement and not restart until

communication has been re-established and it is safe to do so.
