Rail delays have now cleared after a train hit an 'obstruction' on the mainline near Darlington on Wednesday (March 13). 

Trains between London and Edinburgh were severely delayed and rail replacement bus services were in place yesterday evening, due to a train hitting an item between Northallerton and Darlington. 

The incident happened at about 7.35pm, which saw a knock-on effect on train timetables for the remainder of the evening, with some trains to parts of the North East cancelled as a result. 

No further details about the 'obstruction' have been released by National Rail or any rail companies following the incident, but the obstruction was cleared by 3.15am. 

It's understood that a train was damaged during the incident - which needed repairing. 

During the incident, it disrupted LNER, Lumo and TransPennine Express services.

A spokesperson for LNER said at the time: "Due to a train hitting an obstruction between Darlington and Northallerton, services running through these stations may be delayed.
