TRAINS from Cheltenham to London came to a halt yesterday after a signal failure in the Swindon area.
Passengers were left stranded after signalling problems around 7.30am between Didcot Parkway and Bristol Parkway stopped all trains between Gloucestershire and London for more than three hours.
Trains resumed service around noon, although it took nearly two hours to clear the backlog.
A Network Rail spokesman said: "A major signalling failure meant trains were currently unable to run through the Swindon area.
"Engineers worked at a number of locations to rectify the fault and get trains moving as quickly as possible."
