GSM-R user procedures (cab radio Version 2)

The signaller (or operations controller) will announce, at the beginning of the recording,

that the message is a broadcast call and will ensure that the end of the recording is clearly

identified. This will make late entrants or those leaving the pre-defined broadcast area

aware that they have received only part of the broadcast call.

The cab radio automatically answers broadcast calls and speech is relayed through the

loudspeaker. Those receiving a broadcast call only have to listen to the broadcast, and

take the relevant information that is likely to affect their train or prove useful to other

members of staff or passengers on the train.

2.3.4 Railway emergency group call

The network will give a railway emergency group call the highest priority. Someone using

a cab radio or a fixed terminal may make a railway emergency group call.

Once an emergency group call begins all GSM-R users within a certain area will

automatically be connected to the call. The call can only be ended by the person who

made it or someone using a fixed terminal.

2.3.5 On-board communication

This function allows onboard members of staff to use the GSM-R equipment to

communicate directly with each other providing that they have a GSM-R cab radio and

have registered their function or role.

2.3.6 Public address announcement

This allows the signaller to make a call over a train’s public address (PA) system. This is

necessary on all driver only (DO) passenger services.

The signaller can use this function if a driver’s safety device (DSD) alarm is received.

They can ask any railway staff travelling on the train to contact the driver.

2.4 Operational text messages

A number of operational text messages have been developed to improve communications

between drivers, signallers and controllers.

From the fixed terminal the signaller can send:

 Contact signaller.

 Wait (in response to a standing at signal message from the cab radio).

From the cab radio the driver can send:

 Standing at signal (SG).

 A DSD alarm sent automatically by the cab radio if the driver becomes incapacitated

or fails to reset the vigilance device

From the fixed terminal the TOC controller can send:

 Contact xxxxxxx Control.
