A nationwide fault with the communication system is affecting all railway lines.
The system is used by train drivers and signallers and means that trains are subject to delay.
The GSMR system allows for communication between trains and signallers, allowing for safe movement of trains across the network.
The problem is currently being investigated.
Please see National Rail for the latest travel advice.
Here are the latest details:
12:05 – Issue resolved
The issue with GSMR is now fixed, and trains can run normally again; minor disruption may occur across some parts of the network.
09:30 – Update on delays
The delays are being caused by trains leaving their depot at the start of service. However, once running, trains can run normally.

Is this the same World Class organisation that also has repeated signal failures, repeated overhead line failures and repeated track defects and has been served improvement notices by the ORR and will be a key player in Great British Railways ?
