Railway workers are to stage an additional one-day strike on July 27 as part of an ongoing dispute over pay, jobs and conditions.
The national strikes which lasted for three days caused disruption for millions of commuters of the country.
The RMT union announced strike action after it rejected a pay offer from Network Rail, which it described as "paltry.”
It also said it would consult other unions with mandates for strike action in the coming days.
When is rail strike due to start?
Network Rail members will strike from 2am on Wednesday July 27 for 24 hours.
While members on the other 13 train operating companies will take action from 0.01am until 11.59pm on the same day.
Why are rail workers striking?
The union, whose members include everyone from guards and signallers to catering staff and cleaners, is looking for a pay rise of at least 7%.
It also wants a written guarantee from Network Rail that no compulsory redundancies will be made as part of planned reforms.
Which rail companies are affected?
The following companies - which run through London - voted for strike action, and will likely not be running services during the 24 hour walkout.
- Network Rail
- Chiltern Railways
- Cross Country Trains
- Greater Anglia
- East Midlands Railway
- Great Western Railway
- South Eastern
- South Western Railway
- Avanti West Coast
- West Midlands trains
- Govia Thameslink Railway - which includes Southern and the Gatwick Express.
Which routes will likely be affected by the train strikes?
As well as trains which run into London - such as LNER and Avanti West Coast - five commuter trains companies have voted for strike action, and therefore all of their routes will be affected.
- Chiltern Railways: From West Midlands and Bucks through north-west London (Harrow & Ruislip) to Marylebone.
- c2c: Essex through east London (Upminster, Rainham, Barking, Dagenham, West Ham, Limehouse) to Fenchurch Street.
- Greater Anglia: From East Anglia through north-east London (Tottenham Hale, Stratford, Romford, Hackney) to Liverpool Street.
- Southeastern: From Kent and Sussex through south-east London (Bromley, Bexley, Greenwich, Lewisham, Southwark, Croydon, Lambeth) to Victoria, Charing Cross, London Bridge and Cannon Street.
- South Western Railway: From the South West through south-west London (Richmond, Wimbledon, Kingston, Sutton, Wandsworth, Clapham Junction) to Waterloo.
- Govia Thameslink Railway (which includes Southern and the Gatwick Express): Routes from London Bridge, Victoria, and from Bedford and Cambridge through St Pancras International.
What is the RMT saying about the strikes?
RMT general secretary Mick Lynch said: "The offer from Network Rail represents a real terms pay cut for our members and the paltry sum is conditional on RMT members agreeing to drastic changes in their working lives.
"We have made progress on compulsory redundancies.
“But Network Rail are still seeking to make our members poorer when we have won in some cases double what they are offering, with other rail operators.
"The train operating companies remain stubborn and are refusing to make any new offer which deals with job security and pay.
"Strike action is the only course open to us to make both the rail industry and government understand that this dispute will continue for as long as it takes, until we get a negotiated settlement.
"The public who will be inconvenienced by our strike action need to understand that it is the government’s shackling of Network Rail and the TOCs that means the rail network will be shut down for 24 hours.
"We remain open for further talks."
What is the Department for Transport saying?
Transport Secretary, Grant Shapps said: “The railway must reform and modernise, and yesterday the RMT were offered a fair deal which would see salaries of their members rise by up to 8% after two years to deliver just that.
“Yet the RMT has already opted for more destructive strikes and is hellbent on causing further misery for people across the country.
“The average rail worker already earns £44,000, significantly more than the people who will be most impacted by their walkout – the very same people who stumped up £600 per household to keep the railway running throughout the pandemic and ensure not a single person lost their job.
“It’s clear now, however, that no deal was ever going to be good enough for the RMT, and the negotiations over recent weeks have merely been for show while they plan how best to cause further chaos.
“Chaos cynically timed for the day before the Commonwealth Games begins, in a bid to disrupt the travel of thousands trying to attend an event the whole country is looking forward to.
“The industry is already on life support and by insisting on working against its employers, instead of with them, the RMT risks pulling the plug for good.”
