TRAINS going towards London Paddington from Oxford have been cancelled and delayed this morning. 

It comes after Great Western Railway launched a new timetable yesterday.

They promised to slash journey times on key routes, like Oxford to London, and increase seating. 

But on the day that commuters are hopping on board the improved services for the first time, many trains have been cancelled and delayed because of a fault with the signalling system at Maidenhead station.

It means that fast trains coming from Hereford, Worcester Shrub Hill, Oxford, Cheltenham and Didcot through to Paddington are delayed by half an hour, with some even being cancelled.

GWR said a normal service is expected to run again from 9am, but the 9.02am train from Oxford to Paddington has been cancelled - according to the live departure boards.
