Additional information:

Engineers from gas distribution company SGN are on site working to rectify the problem as quickly and safely as possible. Network Rail and train operators are working together to manage the impact on passengers, but normal services cannot operate until the leak has been repaired because the railway falls within the safety exclusion zone.

Severe disruption is expected to services that would usually travel between Didcot and Reading, and passengers are being warned that trains able to run either side of the affected area will be extremely busy.
