Update, 5pm, Sunday, February 12: The line has now reopened, after a temporary retaining wall was built by Network Rail engineers – a 5mph speed restriction is in place past the bridge. Click the link below for more details
Train services on the Cotswold Line are being disrupted for a third day after debris from a collapsed retaining wall on a bridge landed on the tracks between Oxford and Hanborough.
The collapse occurred during the early evening on Friday, February 10, with the 17.34 from London Paddington to Hereford suffering damage when it ran into the debris at the Yarnton Road overbridge at about 6.35pm. More than 360 passengers on board had to be escorted along the track to another train to be rescued.
As a result, an emergency timetable was implemented, with buses replacing trains at stations between Oxford and Moreton-in-Marsh.
The line was blocked all day on Saturday and was expected to remain closed all day on Sunday, while Network Rail engineers carried out work to stabilise the road embankment and repair the retaining wall.
GWR tickets are being accepted by West Midlands Railway, Avanti West Coast, Chiltern Railways and CrossCountry Trains to allow passengers between Worcestershire and London and Worcestershire and Oxford to travel via Birmingham.
Passengers can also use GWR services via Swindon and Gloucester to travel between Worcester, Reading and London.
