Train services to Oxford and Didcot have been disrupted after emergency services were called to a person being hit on the railway line.

Disruption continued into Sunday morning with GWR stating engineering works overran between Didcot Parkway and Bath Spa.

Some lines were unable to be reopened with the disruption expected to last until 11am, while other trains were reduced to 50mph due to the strong winds from Storm Isha.

Train services between Didcot Parkway and Bristol Parkway via Swindon may be cancelled or delayed.

It comes after Network Rail confirmed that a train struck a person on the line on Saturday evening.

A GWR statement said: "Due to emergency services dealing with an incident between Reading and London Paddington, all lines are blocked.

"Train services running to and from these stations will be cancelled, delayed by up to 90 minutes or terminated at and started back from Reading." 

GWR said it is "exploring the possibility of operating a Didcot Parkway to Reading and a Slough to London Paddington shuttle service".

GWR, Network Rail and British Transport Police have been contacted for more information.

It comes as Chiltern Railways has announced late night engineering works will be taking place between Oxford Parkway and Oxford on Saturday, January 27 after 11.05pm.
