NO TRAIN services are currently operating in the Swindon area due to a major signalling failure.

This problem is affecting all routes through Swindon. Services between South Wales and London Paddington in both directions will be either diverted via an alternative route, such as Westbury, with increased journey times, or cancelled.

Services between Bristol Temple Meads and London Paddington in both directions will also be either diverted via an alternative route with increased journey times, or cancelled.

Services between Cheltenham Spa and Swindon will also be cancelled. Replacement road transport has been ordered.

A spokesman for train operator First Great Western said the problem was caused by a power outage which has affected signals.
