Oxfordshire rail works scaled back after service failure
Work on the Great Western mainline through Oxfordshire has been temporarily scaled back after commuters were disrupted by failed signalling.
Network Rail said engineers carrying out piling works had hit a power cable on Monday 6 October which caused the problem.
The firm said: "We have stopped piling until we have reviewed the process that caused the problems."
The work forms part of Network Rail's £1bn rail electrification project.
The power failure resulted in a severely reduced service into Paddington, adding up to an hour to a journey.
Services to and from the west of England, Swansea, Bristol, Oxford, Reading, Cheltenham Spa and Worcester were also affected.
