Around 200 Network Rail workers are spending this Christmas upgrading the points at Peterborough.
From after the last train on Christmas Eve until before the first service on Monday 27 December, engineers will be working around the clock to renew sections of track and the points on a railway junction just north of Peterborough station.
The work will make sure passenger and freight trains can continue running safely and reliably on the East Coast Main Line, as well as the slower Stamford lines. It will also help to prevent points failures in the area, which can lead to disruption to services.
This work has been carefully planned so it can take place when no timetabled trains are running on Christmas Day and Boxing Day. This means teams can safely carry out the improvements before trains resume.
Additional work will take place overnight on Saturday 1 January to renew more of the track in the area. Engineers will also adjust the overhead line equipment to make sure it aligns with the new track.
There will be some changes to early morning services on Sunday 2 January. Buses will replace Thameslink trains between Peterborough and Hitchin until 07:30.
Rob Anthony, Programme Delivery Manager for Network Rail, said: “Upgrading the points and track in Peterborough on Christmas Day and Boxing Day means that we can carry out most of the improvements without impacting on passengers.
“I’m looking forward to working with my team over Christmas on this vital project so that train services can continue running safely and reliably for years to come.
“The complex project continues into the New Year and we’ve carefully planned it to minimise disruption as much as possible. Buses will connect passengers who need to travel on early morning services between Peterborough and Hitchin on Sunday 2 January.”
