Repair work on an unsafe railway viaduct that has been closed for nearly two months is ‘on target’ to be completed by June 10, Network Rail says.

Nuneham Viaduct, which carries the main line over the River Thames east of Abingdon, has been closed since April 3 after significant movement was detected in the viaduct's structure.

Claudia Philps, programme manager at Network Rail, said engineers were ‘working incredibly hard’ to meet the deadline to reopen of June 10.

She told the BBC: "We have a lot of people working incredibly hard, 24/7, making sure that we do meet that [deadline].

"We have engineers, crane operators and machine operators all working in harmony to create that really consistent programme. We are on target."

Engineers have been forced to rebuild the south abutment where a huge crack has formed.

The closure of the Didcot to Oxford line has caused significant disruption with more 100 passenger services cancelled a day.
