A nationwide fault impacting train services has been resolved.
Rush-hour trains across the north and north-east were at risk of last-minute cancellations this monring.
The whole of the UK network, including ScotRail services, was impacted by an unexpected fault with the radio system between the driver and the signaller.
ScotRail said all of its services were subject to delays or cancellations until around 9am.
However, the majority of services north of the border continued to run to schedule.
Customers were warned there could be a knock-on effect throughout the day due to delays further south.
Some also reported problems accessing live travel updates online, which are controlled by a UK-wide system.
ScotRail spokesman David Ross shared: “When you check individual services things are operating normally.”
Radio system fault impacting trains
The fault meant trains were not able to automatically login to the railway radio system at the start of their journey.
Instead, the drivers had to do this manually which was causing a few minutes of delay at the start of journeys.
An update shared online from ScotRail earlier stated: “Due to a national fault with the radio system between drivers and signallers, services are subject to delays.
“Please note that this does not affect the safety of train running as alternative methods are in place.
“Speak to staff or press help points for further information.”
They added: “Our colleagues at Network Rail are experiencing an industry-wide problem with communications systems.
“Thankfully ScotRail services are operating well, with some minor delays in places. Please check before you travel.”
A post shared by Network Rail Scotland stated: “We’re dealing with a national fault affecting the driver – signaller communication system. It’s causing disruption to services across Scotland, England and Wales.
“Our engineers are working to fix the fault as quickly as we can. We’re sorry if your journey’s affected.”
The issue was resolved by 10am and all services resumed as normal.
