Buses are replacing trains between Corby and Kettering this morning after a bridge collapsed in Leicestershire.
There are currently no trains between Leicester and Loughborough after the incident at Barrow upon Soar, causing chaos across the East Midlands Trains network.
The incident has also caused delays heading south from Kettering through Wellingborough to London St Pancras.
A Network Rail spokesperson said: “Owing to a bridge collapse at Barrow upon Soar, train services between Leicester and Loughborough will be disrupted today.
“This will affect journeys on the London St Pancras/Nottingham/Leicester and the Leicester/Lincoln/Grimsby routes.
“We are working to clear the track as quickly as possible and reopen the line, however passengers are advised to check before they travel and allow extra time for their journeys.”
Passengers have been warned their journey time could increase by up to 90 minutes.
