Disruption to/from London St Pancras International due to a broken down freight train
Latest Information: 1530
A broken down freight train between Bedford and Wellingborough means some lines are closed and we are running a reduced service.
A reduced service will run between Sheffield and London St Pancras International.
Our trains departing 49 minutes past the hour from Sheffield to London St Pancras International and our trains departing 26 minutes past the hour from London St Pancras International to Sheffield are suspended.
Our services between London St Pancras and Corby will operate between London St Pancras and Kettering only.
A rail replacement bus service will operate between Kettering and Corby connecting into and out of trains at Kettering.
You can expect delays up to 20 minutes on all our trains to/from London St Pancras International.
If you are travelling on a Sheffield/London service that has been cancelled, you should travel via the following routes:
Sheffield to/from London Kings Cross via Doncaster,
Derby to/from London Euston via Birmingham,
Nottingham to/from London Kings Cross via Grantham,
Leicester to/from London Euston via Nuneaton
Other operators will accept East Midlands Trains tickets. These alternative routes will remain in place until further notice.
Advance purchase tickets may be used on other trains, than booked.
Network Rail have advised that staff are on site and have examined the broken down freight train. Movement of the train is not expected to take place until over night on Thursday 20 August and our services are likely to be affected until the end of today.
A Network Rail spokesperson said: “We would like to apologise for the inconvenience caused following a mechanical issue with an engineering [freight] train in the early hours of the morning. The high output train was scheduled to renew track to the south of Wellingborough overnight when it suffered significant damage to the axle box. Given the extent of the damage and with the incident having occurred close to the start of morning services, the train has remained on the line throughout the day. Engineers have been on site working to fix the problem today and the train will be removed overnight, with normal service resumed from tomorrow morning.”
We apologise for the delays to your journey today
