GSM-R user procedures (cab radio Version 2)

the cab radio will attempt to reboot five minutes after displaying the failure. It is

permissible to manually re-boot the radio (when safe to do so), to attempt to clear the fault.

These types of faults must be reported.

 If attempting a manual re-boot by tripping and re-setting the cab mobile circuit

breaker; if a battery back up is fitted, the drivers control panel must be switched off

first.

If the fault message relates to a non-service affecting fault, your train will be allowed to

enter or remain in service. However, you will need to acknowledge the fault message by

pressing . A reminder of this fault will remain on the display until the radio is switched

off.

9.2.6 If the cab radio does not find the network

If the cab radio fails to find the GSM-R GB network in an area that normally has coverage,

you should first try to establish whether there is a network problem at your location (if you

have not already been informed by your control or in a broadcast from the signaller).

If you are able, try checking the rear cab mobile, if this also fails to find the network the

likelihood is a network failure.

In this circumstance you must contact the signaller controlling the movement of your train

and if there has been no report or confirmation of coverage problems at your location you

should treat the cab radio as defective and follow the process identified in your company’s

contingency plan.

9.2.7 The radio connects to the wrong network

If you are using the GSM-R cab radio in Great Britain, it should default to the ‘GSM-R GB’

network. However, in the unlikely event that it logs on to another network, you can choose

the GB network manually. You can select the GSM-R GB network using the menu:

‘Settings’, Select network’

, , and choose the GSM-R GB network from the list.

9.2.8 Cab radio displays foreign language

The radio will normally use English when powered up. If the previous user has changed

the language and the cab radio has been switched off but not powered down, it may

display a foreign language. In this case you can set the language to English again using

the menu short cut.
