Work continues on the £1.5 billion upgrade of the Midland main line to improve journeys for all those using the route.
On 4/5 and 11/12 July, Network Rail will commission and test two new substations on the route between Bedford and Ampthill to help to improve resilience on the railway, as well as provide the power needed to allow more trains to run in the future.
Work will also take place to improve the track on the route, as well as to install further overhead line equipment.
To allow the work over these weekends to take place safely, some lines on the Midland main line will be closed. Network Rail, East Midlands Railway and Govia Thameslink Railway are urging passengers to check before travelling whilst this work takes place.
Gavin Crook, principal programme sponsor for Network Rail, said: “This work is a key part of the Midland Main Line Upgrade, which will bring significant benefits for passengers when complete.
“Over these weekends, we’ll be installing further overhead line equipment, as well as commissioning two new substations, which will help provide more power for the railway.
“We urge people to continue to follow Government guidance, which is to avoid public transport if possible. However, if you must travel, please check before travelling and allow additional time for your journey.”
