The UK's biggest rail strike in a generation is expected to bring much of the country to a standstill this week.
Half of Britain's train lines will close over the three-day walkout, with many running at just 60% of usual service on the interim days.
Despite last-ditch peace talks between the Government and union leaders, more than 50,000 members of the RMT union are expected to strike on Tuesday, Thursday and Saturday.
The number of passenger services on the strike days is expected to be limited to around 4,500 compared with a usual daily average of 20,000.
Here is the reduced timetable published by National Rail for the strike days:
Avanti West Coast
Avanti says it will be running a "significantly reduced timetable" and is offering customers with existing tickets for travel from Tuesday 21 June to Sunday 26 June a full refund with no admin fees from their point of purchase, or the option to postpone travel.
The Essex Thameside network will be operating a reduced service from 07:30 – 18:30 on strike days, equating to less than a third of normal service levels, and consisting of two trains per hour from Fenchurch Street to Shoeburyness via Laindon, and two trains per hour from Fenchurch Street to Pitsea via Rainham. No trains will run via Ockendon or Chafford Hundred
Although Caledonian Sleeper staff are not participating in the strike action it does have a significant impact on operations and all services have been cancelled during the strike week.
Chiltern Railways is advising passengers to avoid all but essential travel. A significantly reduced timetable will run from Tuesday to Saturday, and no services will operate north of Banbury or to Oxford. Services will finish earlier on Monday 20th June and start later on Sunday.
The company said: "On strike days there will be extremely limited availability of staff and as such we will not be able to operate services on most routes. There will be no replacement buses or alternative travel provided. Unfortunately, as we will not be able to position our fleet how we normally would, the significant impact of the strike will also be felt on non-strike days."
Advance tickets for the three strike dates have been suspended, and just a few of the regular train routes will be running. Here is a map of which services will be running, at reduced capacity:
East Midlands Railways
Only one train per hour will run between Nottingham and London, one each hour between Sheffield and London and Corby and London, and one per hour between Derby and Matlock, Derby and Nottingham, Leicester and Nottingham - a stopping service - and Nottingham and Sheffield.
The newly opened line is run by Transport for London, which is not part of the mass strike action. However, while not part of the main dispute, there is strike action planned on TfL London Underground services at the same time as part of a separate dispute between RMT and Transport for London. So there will be disruption on the Elizabeth Line in the coming week.
Many stations and routes will be closed, and trains will only be running during limited hours from around 7.15am, finishing in the late afternoon.
A maximum of three trains each day will run on each of the Grand Central routes with the company updating timetables daily here.
Two trains per hour will run between London Victoria and Brighton and London Bridge and Brighton, as well as two per hour between Hove and Brighton, London Bridge and Three Bridges, and London Bridge and Gatwick Airport. Two trains per hour are also expected to run on routes between Victoria south London and London Bridge and south London, but just one per hour on lines between Services between King’s Cross and Peterborough, Cambridge and Ely.
Watch: Not too late to call off rail strike, says PM
Great Western Railway
GWR has cut many services from its timetable and has published a map of intended routes but advises customers to check on the day of travel if making essential journeys. It encourages users to stay at home is journeys are not essential.
A vastly reduced service will be running, and only those connecting London routes. No regional or branch lines trains and no rail replacements buses will be in service.
A Heathrow Airport spokesperson said: "Rail services across the UK are expected to be severely disrupted on 21, 23 and 25 June due to industrial action. On these days there will be a very limited Heathrow Express service running from 07:30 to 18:30 every 30 minutes. However, these trains are expected to be extremely busy. Additionally, on 21 June London Underground services will be severely disrupted due to industrial action."
Paragon Station in Hull will be one of the few major stations where all services are cancelled during the planned strikes. This includes services run by TransPennine Express, Northern and Hull Trains.
The station will be open on Wednesday and Friday, though commuters are being warned to expect alterations to timetables on these days. Commuters are being urged not to travel by train this week and to make alternative arrangements. Additionally, some services are not providing any alternative means of transport.
The operate will run two trains per hour between London and Edinburgh, and one an hour from London to Leeds. The last train from London King’s Cross to Edinburgh is at 14:00, the last train from London King’s Cross to Leeds is at 15:05 (15:06 on Saturday), the last train from Edinburgh to London is 12:30, and the last last train from Leeds to London 15:45.
Trains between London Euston and Northampton will run twice an hour on strike days, no trains will run from Euston to Crewe or on the Marston Vale and Abbey Lines routes. One train per hour will operate from Birmingham to Northampton.
Around half of all services are likely to run between 7.30am and 6pm but TfL are advising people not to travel unless the journey is essenital.
Lumo says it will run as many services as possible, but has published a reduced timetable here.
There will be no Merseyrail train services on Tuesday, Thursday and Saturday. There will also be knock on effects on the day after each industrial action date. On Wednesday and Friday limited rail replacement buses will run until 7am and trains will be reintroduced from 7am.
Routes including Newcastle and Morpeth to Alnmouth, and Sunderland and Newcastle to Hexham and Carlisle, have all been cancelled. Other routes will run on a skeleton service subject to change, with updated timetables being published here.
ScotRail have announced that there will only be five lines running during the strikes. The five lines which are running are as follows.
Edinburgh – Glasgow via Falkirk High: two trains per hour
Edinburgh – Bathgate: two trains per hour
Glasgow – Hamilton/Larkhall: two trains per hour
Glasgow – Lanark: two trains per hour
Edinburgh – Glasgow via Shotts: one train per hour
Trains will run between 07.30am and 6.30pm, with ScotRail warning that the trains will depart their station well before services terminate.
Many commuters into London will be hit by the strikes, with just Only 35 of Southeastern's 180 stations open. No rail replacement buses will serve stations which are closed and travellers have been warned they may be unable to board trains at stations where a limited service is running, especially at locations such as Ashford and Ebbsfleet. The last trains back from London will be much earlier than usual, so there is a risk that not everyone will be able to make their return journey, and services in between strike days are expected to be severely disrupted, especially in the mornings.
Two trains per hour will run connecting London Bridge and London Victoria, to Brighton and Gatwick. All other routes will also be reduced to two per hour from 7.30am until late afternoon.
With Network Rail signallers and more than 2,100 SWR RMT members taking industrial action, SWR will run a dramatically reduced timetable on strike days, with significant parts of the network closed. A late-starting Sunday level of service will operate across the network all week.
Seven stations will close altogether, and a skeleton service will run on major routes.
Transport for London
London-wide strikes will affect Tube and other TfL services on Tuesday and services until mid-morning on Wednesday.
Transport for Wales
TfW is not in dispute with RMT, but the industrial action means it is unable to operate rail services on Network Rail infrastructure. On Tuesday and Thursday the only lines running will be a reduced service between Radyr and Treherbert, Aberdare and Merthyr Tydfil, with replacement bus services between Radyr and Cardiff Central. On Saturday there will be a reduced service between Radyr and Treherbert, Aberdare and Pontypridd, with replacement buses in operation between Radyr and Cardiff Central, and between Pontypridd and Merthyr Tydfil due to the ongoing transformation work for the South Wales Metro. All other services will be suspended, as signalling and other infrastructure work is managed by Network Rail, who are impacted by the industrial action.
West Midlands Railway
WMR will be running a very limited service and some parts of the network will have no trains. No trains will run between Leamington and Nuneaton, Birmingham and Leamington, Birmingham and Kidderminster and Worcester, Birmingham New Street and Hereford, Shrewsbury and Walsall, and all other routes will only run one or two trains each hour.
