Rail strikes planned for this week will go ahead after last-ditch talks failed to resolve a dispute over pay, jobs and conditions.

Thousands of members of the Rail, Maritime and Transport union (RMT) at Network Rail and 13 train operators will walk out on Tuesday, Thursday and Saturday in the biggest industrial action on the railways for a generation.

Services across the UK will start to be affected from Monday evening, with just one in five trains running on strike days, primarily on main lines and only for around 11 hours. London Underground workers are also on strike on Tuesday.

Final confirmation of the strike action was confirmed by RMT general secretary Mick Lynch this afternoon (June 20).

Politicians, including Transport Secretary Grant Shapps, had called for the “damaging” strike action to be called off.

Passengers travelling in the Watford area will be significantly disrupted by the strike action.

London Northwestern, which operates services to and from London Euston via stations including Watford Junction and Bushey, has warned customers should only travel if “essential”.

On strike days (June 21, 23, 25) LNR says two services will be running per hour between London Euston and Northampton. The last train will depart Euston at 5.30pm. There will be no LNR trains departing Watford before 8am.

On June 22 and 24, there will also be a “significantly reduced” LNR service with services not beginning until 7.30am at the earliest and ending earlier than usual.

There will be no Abbey Line service between Watford and St Albans between June 21 and 25.

Jonny Wiseman, LNR customer experience director, said last week: “We will be operating a very limited service all through the week and we are asking customers to only travel with us if their journey is essential and no other transport option is available to them.

“Passengers holding tickets or season tickets will be entitled to refunds and should visit our website for information.”

More details on LNR’s timetables during the strike action can be found here or via the National Rail website.

Govia Thameslink Railway says two trains will run per hour via Radlett and other Thameslink stations on strike days with late starts and early finishes, with a Sunday service on June 22 and 24. Southern and Chiltern services will also be disrupted.

TfL workers will also strike tomorrow (Tuesday June 21).
