Grantham and Nottingham rail services resume after bank slip work

Network Rail said "very heavy rain" caused the bridge's retaining wall to collapse

Train services have resumed after part of a Lincolnshire railway bridge was damaged by a bank slip which disrupted a line between two counties.

However, Network Rail said trains between Grantham and Nottingham are restricted to 20mph until repair work has been completed on Monday morning.

Rain had caused the bridge's retaining wall to collapse at Allington, five miles from Grantham, on Friday.

Replacement bus services were put in place during the rail disruption.

Keith Lumley, from Network Rail, said: "The line reopened as planned this morning, with a 20mph speed restriction in one direction.

"We are doing more work overnight and fully expect the speed restriction to be lifted in time for the start of services tomorrow morning."

During the disruption, trains between Nottingham and Skegness were affected, with a replacement bus service between Nottingham and Grantham.

East Midlands Trains' services between Liverpool and Norwich did not stop at Grantham in either direction.
