Network Rail is warning of disruption on the West Coast Mainline this weekend, because of engineering work on much of the line.
Track renewal work at Weedon in Northamptonshire means trains will be diverted via Northampton. Network Rail says all of the work will mean either longer journeys or bus replacement services, and is advising passengers to check before they travel.
The work begins late on Friday evening, and will continue through until Tuesday morning.
"These upgrades will help to provide a more reliable railway which is essential as more people choose to travel by train. There is never a good time to carry out work of this nature but we have worked with the train operators to plan it to cause the least amount of disruption and make sure passengers can plan or make alternative arrangements. I apologise for any inconvenience caused."
