Terminating

STOP EMERGENCY

this case, at the end of the short confirmation tone you will hear a ‘busy’ tone and see

the message ‘busy’ on the cab radio display. Holding down the PTT until the other

user releases their PTT will not work. You have to release your PTT and press it

again when you see the “PTT” prompt.

Railway emergency group calls made by the signaller will be announced with the following

message:

“This is a railway emergency call. I repeat, this is a railway emergency call, from the

signaller at ………….to all trains in the …………. area.”

Unless absolutely necessary, you must only listen to the voice communication. If you try

to take part in the railway emergency group call it may prevent vital safety-related

information from being given (this is because using the PTT and getting a voice connection

will prevent anyone else speaking at that time).

So, if you receive a railway emergency group call, you must listen to the message, and

only take part in the call, if asked to do so by the signaller or if you need to provide vital

information about the emergency.

Phase 3 - ending of the call

The signaller with ‘Lead Responsibility’ will end the railway emergency group call, but only

when they are sure that the situation is under control. Once the emergency

communication has been completed, the signaller will signal the end of the call by stating:

“…end of railway emergency group call.”

If you received the railway emergency group

call, you must not move your train until the

railway emergency group call has ended, you

are sure your train is not affected by the

emergency and you have not been instructed to

remain at a stand.

7.1.3.1 Unexpected termination of the railway emergency group call

For example if you leave the railway emergency group call area before your train has been

brought to a stand, the network will end the call to your cab radio. However, you must

continue to bring your train to a stand and contact the signaller using a point to point call

and await further instructions.

7.1.3.2 Entering an area once the REC has commenced

If you have stopped your train upon entering the railway emergency group call area after a

call was set up, and you missed the beginning of the message, attempt to gain as much

information as possible by listening to the call. You must not move until the railway

emergency group call has been terminated, you have received no specific instructions not

to move and you are sure your train is not affected by the emergency.

7.1.3.3 If you do not understand the message or the message seems incomplete
