RMT Tube strikes scheduled for this week may have been cancelled - but separate industrial action is still set to impact Londoners this weekend.
A strike hitting London Northwestern Railway (LNR) means there will be limited services from London Euston this Friday and Saturday.
Just one train per hour will run between Euston and Northampton, and Euston and Birmingham via Northampton due to low staff numbers caused by the TSSA union walkout.
Other routes in the Midlands will be cut entirely, while there will be no trains running after 7pm on Friday May 22 or before 7am on Saturday May 23.
There will also be some minor disruption to services on the morning of Sunday May 24 due to the displacement of trains.
Ian McConnell, LNR managing director, said: “We encourage TSSA to continue talks with us to reach a resolution to this dispute. This strike action will cause disruption to our customers with a significantly reduced timetable in operation on both dates.
"We are doing all we can to minimise the impact as far as possible and apologise to customers for the inconvenience. However, where services are running, we advise customers to only travel if necessary and to allow more time for their journey."
It comes after the news that one in seven train services will be axed on Avanti West Coast’s busiest routes, with the operator citing a Government request to reduce spending.
Around 38 daily weekday services will be removed from timetables for six weeks over the summer, starting from July 20.
The company usually runs 248 daily services on the affected routes, connecting London Euston with Birmingham, Liverpool and Manchester, but Avanti said it proposed removing some services with lower demand following a request from the Department for Transport (DfT) to cut costs.
Avanti have said that the measure will cause minimum disruption to passengers and will not reduce revenue.
An Avanti West Coast spokesperson said: “From July 20 to August 28, we will be operating an amended timetable between London and Birmingham, Liverpool and Manchester on weekdays.
“To ensure minimal impact to those travelling between the affected dates, these changes will only affect routes on which we operate more than one train per hour, during typically less busy periods of the day - maximising alternative journey options.
“We’d like to encourage customers planning to make journeys during this time to plan ahead, and thank them for their understanding.”
The RMT union called off Tube strikes earlier this week, sparing hundreds of thousands of Underground users more travel misery.
The rail union had been due to press ahead with two 24-hour walkouts over the introduction of a four-day week, before chiefs met on Monday morning to call off the industrial action.
A union spokesperson said: "At the 11th hour the employer has shifted its position allowing us to further explore our members' concerns around the imposition of new rosters, fatigue and safety issues.
"The dispute is not over and more strike action will follow if we fail to make sufficient progress."
The union did however bring forward planned strikes in June, which were due to take place on the 16 and 18 - they are now set to start on Tuesday June 2 and Thursday June 4.
