Network Rail had to carry out emergency repair works following the derailment of a freight train at Barrow on Soar (between Leicester and Loughborough) on 27th December.
Train services will be unable to call at Barrow Upon Soar until later notice because further remedial work is required following the derailment of a train carrying over 1,000 tonnes of stone.
I apologise to all those who have been inconvenienced by this work and thank passengers for their continued patience. Removing the wagons safely is a complex job and this location is not easily accessible, all of which has added to the time it has taken to complete.

- Over 23,000 seats to be provided in each direction to and from London (around 50% of normal capacity)
- Tickets which can be used on other train services, including Virgin, East Coast, Greater Anglia, TransPennine Express, Northern and CrossCountry.

East Midlands train drivers have been criticised by the operator for being "hell bent on trying to disrupt the Olympics".
The comments from the Managing Director of East Midlands Trains, David Horne, come after the drivers' union ASLEF confirmed that it will take further strike action during the games.
A walk-out is planned for the 6, 7, and 8th August, which is in the middle of the Games when Usain Bolt, the fastest man on earth and one of the most anticipated competitions of London 2012 is taking place.
The strike action is due to a row over pensions, East Midlands Trains have accused ASLEF on going back on a deal brokered in talks last week:
"If ASLEF does not have a change of heart, it will be remembered long after London 2012 as the union who tainted the pride of Britain in disrupting such a once-in-a-lifetime sporting event."
– David Horne, Managing Director of East Midlands Trains
However the union ASLEF said it was deeply saddened that the union finds itself in this position:
"ASLEF is disappointed that recent talks with East Midlands trains did nothing to address major pre-existing concerns ASLEF has in relation to its dispute between EMT and ASLEF members."
"ASLEF is deeply saddened that the union finds itself forced into this position by East Midland at this time."
– ASLEF Spokesperson
