GSM-R user procedures (cab radio Version 2)

You must listen to the message being announced and, if necessary, pass on the

information to other onboard members of staff or passengers on the train.

 A broadcast call is normally a pre-recorded announcement and might be joined (or

left) by the cab radio part-way through if the train enters/exits the group call area. As

a result, the start and end of the message will be as described above to allow you to

know whether the entire message has been received.

If only part of the broadcast call was received and you are unsure of its relevance to you,

then you can seek clarification from the signaller.

7.2 Receiving operational text messages

7.2.1 ‘Contact signaller’ message

If the signaller needs to speak to you, and it is not

urgent, the signaller will ask you to call him/her

using the ‘Contact signaller’ operational text

message.

You will hear a short alert tone to let you know

about the contact signaller message. The

message will be shown on the display along with

who sent it.

as possible as long as you can do this safely.

You can make a call to the signaller by simply pressing . (See section 7.3.1).

 If you respond by pressing the button, there is no guarantee that the call will be

connected to the signaller who sent the ‘Contact signaller’ message as the train may

have moved out of that signaller’s area by the time you respond.

by your Train Operating Company to contact

you. Response to this message is the same as
