LONDON, Dec. 6 (Xinhua) -- Some services across the UK's National Rail network were disrupted on Friday morning due to "a nationwide fault with the communication system used between train drivers and signalers."
Routes to London's Heathrow Airport and Gatwick Airport were among those affected, along with services operated by Northern, South Western Railway, and Transport for Wales.
Travelers across the country faced short-notice cancellations and alterations due to the knock-on effect on the timetables.
According to a statement by the National Rail, the issue mainly affected trains registering to enter their route for the start of service and deregistering to end their service. ■
