Signal problem hits Glasgow trains
A signal problem which caused major disruption to train services to and from Glasgow Central Station has been fixed.
Passengers earlier faced delays and cancellations on high level services. Low level services were unaffected.
Engineers traced the fault to a power cable in the Polmadie area.
Network Rail said the problem, which developed at about 07:30, had been sorted and services were returning to normal.
A spokesman said: "The fault which caused major disruption at Glasgow Central station this morning has been confirmed as stemming from an issue with a power cable in the Polmadie area which caused the signalling data links to fail.
"The fault has now been isolated and rectified.
"Network Rail apologises for any inconvenience caused".
ScotRail had urged rush hour commuters to make their own alternative arrangements.
All train routes to and from Glasgow Central high level - with exception of Ayrshire, Inverclyde and Paisley Canal - had been withdrawn.
CrossCountry services to and from Central were being delayed by up to 60 minutes.
Virgin Trains were starting and terminating at Motherwell.
