Commuters were facing delays this morning as UK Network Rail experienced a nationwide “communications fault”.
National Rail warned there was a problem affecting the system used by train drivers and signallers earlier today.
It was unclear how long the issue would last, but the rush hour commute has been affected.
A National Rail spokesperson said: “There is a nationwide fault with the communication system used between train drivers and signallers. As a result, services across the National Rail network may be subject to disruption this morning.
“Trains across the network are having to start their journeys later because of this fault and some may also be subject to cancellations or alterations. Please check before you travel, allow extra time for your journey and monitor live departure boards.”
