London train strike: Is there a Tube strike today - which London Underground lines are hit by rail strikes?

Some London Underground lines are facing delays and suspensions today, as strike action by train workers continues to derail passengers’ summer plans.

The Rail Maritime and Transport Workers union (RMT) is leading a 24-hour strike on Wednesday, 27 July by around 40,000 workers.

The Tube isn’t officially part of the strike action, but some lines are experiencing a knock-on effect.

RMT, spearheaded by Mick Lynch, is demanding members receive a pay rise in line with inflation, and improved job security.

A further strike is planned for Saturday, 30 July by Aslef union members.

Which Tube lines are affected?

• Bakerloo line: Suspended between Queen's Park and Harrow & Wealdstone. Good service on the rest of the line.
• District Line: Minor delays between Turnham Green and Richmond. Good service on the rest of the line.
• Elizabeth line: Reduced service between Paddington/Heathrow and Reading, also between Liverpool Street and Shenfield. Good service on the rest of the line.
• Overground: No service between Barking to Barking Riverside; Surrey Quays to New Cross; Kilburn High Road to Euston; Romford to Upminster; and Camden Road to Stratford. A significantly reduced service is operating on the rest of the line.
• Good service on Central, Circle, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly, Victoria, Waterloo & City, DLR and Tram.

Why is the train strike happening?

During talks between Network Rail and unions, workers were offered a 4% pay rise, another 2% next year, and a further 2% if “modernisation milestones” are achieved.

Union leaders dismissed the terms and came back with a demand for pay to rise in line with inflation, which stands at just under 10%.

In a statement on the RMT website, general secretary Mick Lynch said: "The rail industry and the government need to understand that this dispute will not simply vanish.

“They need to get serious about providing an offer on pay which helps deal with the cost-of-living crisis, job security for our members and provides good conditions at work.”

Grant Shapps, the government’s transport secretary, urged trade unions to “stop holding the country to ransom”.

He said: “Union bosses are once again trying to cause as much disruption as possible to the day-to-day lives of millions of hardworking people around the country.

“What’s more, it has been cynically timed to disrupt the start of the Commonwealth Games and crucial Euro 2022 semi-finals, in a deliberate bid to impact the travel of thousands trying to attend events the whole country is looking forward to.”
