Delays of 80 minutes on train journeys through Grantham
Cable theft on the railway at Retford has led to delays of around 80 minutes on journeys between Doncaster and Grantham, according to Network Rail.
Signalling problems have arisen as a result of the theft, causing delays which are expected to come to an end at 3pm.
Services affected are:
* First Hull Trains between Beverley, Hull and London Kings Cross
* Grand Central between Sunderland/Bradford Interchange and London Kings Cross
* Virgin Trains East Coast between Edinburgh/Leeds/Hull and London Kings Cross
A spokesman for Network Rail said engineers are working to resolve the problem. Some services will be diverted.
