signaller

National Rail said the issue was due to a "nationwide fault" with the radio system used between train drivers and signallers.

Network Rail is experiencing a nationwide fault with the radio system between driver and signallers, leading to delays and cancellations to services.

“The driver can report it to the signaller and they have options to clean the rail,” he says.

Giving evidence, Captain Lewis Fox, of 16 Signal Regiment, confirmed that in December 2020 Mr Khalife was awarded the trophy, which was "rare" for a signaller.

After starting his Army career in Omagh, County Tyrone, he moved to England and worked for a time as a Morse code signaller.
