Commuters have been told not to travel from London Waterloo during the rush hour after a fire closed nine platforms.
The lineside blaze damaged cabling outside the station, meaning trains cannot use platforms 16-24.
Network Rail said “significant damage” had been caused to equipment, meaning trains will be delayed or cancelled.
Disruption is expected for the rest of the day while the Thursday morning rush hour may also be affected.
Network Rail said its engineers would be working through the night to fix the damage.
Waterloo is the busiest and largest railway station in the UK.
The platforms which are closed are normally used by trains serving Windsor, Reading, Hounslow, Richmond and Kingston.
However, services from other platforms are also being affected because trains have to be diverted or revised.
- Circular services via Hounslow, Richmond, Strawberry Hill and Kingston have been cancelled
- Trains between Waterloo and Windsor & Eton Riverside are diverted via Kingston
- Trains between Waterloo and Exeter/Salisbury are terminated and will restart from Basingstoke
Passengers were warned that services on other routes may also be subject to short-notice cancellations or delays.
In a joint statement, Network Rail and South Western Railway said commuters were “strongly advised to use alternative routes where possible and check their journeys before travelling at southwesternrailway.com for ticket acceptance and service details”.
Some passengers took to social media to express their frustration at the travel disruption.
One Twitter user described the situation as an “absolute shambles”, while others complained about being given the wrong or no information at all by train station staff.
An engineering train has derailed in south London causing the closure of the Gatwick Express service.
The train partly left the tracks at low speed outside Victoria station at about 03:00 BST.
No Gatwick Express trains are running, while Southern warned its services would be “severely reduced”.
The train has moved and the track will now be “assessed for damage” and repaired if necessary through the night, according to Southern.
Disruption is expected to last throughout Tuesday but Gatwick Express and Southern said a normal service was expected on Wednesday.
The train was stuck across a number of tracks meaning platforms nine to 13 at Victoria were blocked, while services were not able to use the “slow/stopping” lines to and from Clapham Junction.
Some trains were also unable to leave the Battersea depot – further reducing the number of services that could run.
Recovery teams cut the 50-tonne train from its two wagons and lifted it back on to the track using hydraulic jacks.
Trains running through Gatwick Airport were also disrupted by a separate signalling fault and a passenger who was injured as they left a carriage, which led to one platform becoming blocked.
Some commuters took to social media as they found their trains had been cancelled.
Other stations, including London Bridge, also became congested as people tried to find alternative routes.

Leicester Riders won the BBL Play-offs title for a third season in a row by beating the London City Royals 93-61 in the final at the capital’s O2 Arena.
Leicester’s defensive intensity again proved decisive in a final as they held London to just 25 second-half points.
Tim Williams led Leicester’s scoring with 20 points and Jamell Anderson and JR Holder added 17 and 14 respectively.
Matthew Bryan-Amaning crowned a fine season with 19 points for the Royals and Orlan Jackman added 16.
The Royals stayed in touch in the opening two quarters with a Leicester side that has regularly won trophies in the last five years and their former Great Britain player Bryan-Amaning looking to make his presence felt close to the basket towards the end of the first half.
Down just 44-38 when Jackman scored the first basket of the second half, the Royals then conceded 11 unanswered points in a run triggered by Leicester’s Holder and Williams.
After the Riders went on a further 11-2 run, inspired by three-pointers from Anderson and Pierre Hampton, the Royals were 24 behind and they posted just 10 points in a third quarter in which the final was all but decided.
Riders continue dominance
Leicester’s win – in their sixth final in the past eight years – is their third play-offs title and equals the feat of Kingston, Worthing and Newcastle, who also scored hat-tricks in the play-offs.
Leicester coach Rob Paternostro said he had expected a closer contest but believed his team’s improvement in the second half of the season, after the rigours of their European campaign, had been instrumental in the win.
“Coming into the play-offs we became more of a group that was locked-in, especially on defence,” he said. “I’m super-proud of how locked-in mentally they were.
“We just thought that we had to get back on defence – we felt that when our defence was set up, we were going to be really tough to beat in this game. There weren’t many adjustments to make.”
Royals coach Jay Williams said: “We struggled with consistency throughout the season but in the big games we showed up – but today we just didn’t.
“Hats off to the Riders – they came out and executed their game plan and they were consistent the whole time through.
“We played hard but we didn’t play smart and the Riders exploited that. But the main thing is – we didn’t show up.”
Climate activists gathered to mark the end of protests that caused 11 days of disruption across London.
More than 1,100 people have been arrested since campaigners from Extinction Rebellion first blocked traffic in the capital on 15 April.
On the final day of action, protesters blocked roads, climbed on a train and glued themselves together in London’s financial district.
Hundreds of people met in Hyde Park for a “closing ceremony”.
Campaigners sat on the grass next to Speaker’s Corner – widely considered London’s home of free speech – singing and listening to musicians.
Transport for London said all roads are open around Marble Arch.
Skeena Rathor, of Extinction Rebellion, welcomed the “rebels” to the ceremony and described the crowd as “beautiful beings”, adding: “This is our pause ceremony.
“Welcome to the beginning of our pause.”
She invited the crowd to “begin a process of reflection”, adding: “Thank you for what you have done this week. It is enormous. It is beyond words.”
The crowd cheered and clapped when a speaker said “the police were amazing” during the days of blockades.
“We will leave the physical locations but a space for truth-telling has been opened up in the world,” event organisers said on their Facebook page.
“We would like to thank Londoners for opening their hearts and demonstrating their willingness to act on that truth.
“We know we have disrupted your lives. We do not do this lightly. We only do this because this is an emergency.”
Extinction Rebellion is urging the government to “tell the truth” about the scale of the climate crisis. It wants the UK to reduce carbon emissions to net zero by 2025 and a Citizens’ Assembly set up to oversee the changes needed to achieve this.
On Thursday, 26 people were arrested on suspicion of aggravated trespass outside the Stock Exchange and on Fleet Street, bringing the total number of arrests up to 1,130 since the protests began on 15 April, the Met Police said.
Four people stood on top of a Docklands Light Railway (DLR) train while another glued herself to a train.
Five people were arrested on suspicion of obstructing the railway, the British Transport Police said.
Meanwhile, Dame Emma Thompson, who joined the activists on Saturday, has defended flying from Los Angeles to London to take part.
The actress said it was “very difficult to do my job without occasionally flying” but she was “in the very fortunate position of being able to offset my carbon footprint”.
More than 10,000 police officers have been deployed during the action.
Mayor of London Sadiq Khan said the protests had been a “huge challenge for our over-stretched and under-resourced Metropolitan Police”.
The Met said on Wednesday it had imposed new conditions under the Public Order Act on the protest area in Marble Arch, making it a criminal offence to protest outside a designated area or incite others to protest outside of it.
The conditions will remain in force until Saturday.
