A “nationwide fault” disrupting train services due to a problem with a communication system has been fixed after wreaking havoc for commuters on Friday, National Rail has said.
Dozens of services have been affected. Particular problems are affecting London Waterloo, one of the three busiest stations in the UK. Trains to and from Salisbury and Yeovil have been cancelled as a result of communications problems. Many other trains are running 10 to 20 minutes late.
