EPASeverely disrupted London Underground services have spurred Londoners to turn to bikes, buses and black cabs to make their way through the capital.
Tube workers are striking over pay and conditions, leading to the closure of most of the network.
Members of the Rail, Maritime And Transport union (RMT) are staging the walkout until Thursday.
The Elizabeth line and the Overground are operating but are expected to be much busier than usual, said Transport for London (TfL).

Cycle hire company Lime, which has more than 25,000 bikes across London, said it was working to keep as many of them in service.
General manager Kaan Tas said the company knows from experience that demand surges during a strike and in preparation Lime was “stepping up” operations across the city.
These included a team on standby to keep vehicles in service with fresh batteries, repairs or rebalancing overcrowded bays.
There were also extra foot patrols in central London to keep high-demand areas clear and bikes available.

Chris Barnes travels into central London from Ramsgate on the Kent coast five days a week and said the strike would cause his daily journey to become a 6-hour round-trip.
He said he accepted Tube workers “were unhappy, but my sympathy has run out”.
NHS worker Rachel Edwards said she did not agree with the RMT’s demand for a 32-hour week, believing it to be “unrealistic”.
She added: “The country is in such a mess and we all need to pull together and not go on strike.”
Another traveller, Paul Weallans, described the strikes as “a fact of life in London” and hoped a resolution would “not be a long time coming”.
EPA‘Fair and affordable’
The RMT union said its members were not going on strike in order to disrupt small businesses or the public but “because of TfL management’s refusal to consider a small reduction in the working week in order to help reduce fatigue and the ill health effects of long-term shift work on our members”.
A spokesperson added: “We believe a shorter working week is fair and affordable particularly when you consider TfL has a surplus of £166m last year and a £10bn annual operating budget.”
The union said there were 2,000 fewer employees on the Underground since 2018, with members “feeling the strain of extreme shift patterns”.
London Underground, which runs the Tube network, described union demands for a cut in the 35-hour week as “simply unaffordable”.
Director of customer operations Nick Dent said a reduction to a 32-hour week would cost the company “hundreds of millions”.
He also said this week’s actions would be “very damaging” for London Underground, as separate groups of workers are walking out on different days.
Information about which Tube lines are affected by industrial action can be found on TfL’s website.
TfLThe prime minister’s official spokesman said Londoners would “rightly be fed up with the disruption” and the RMT and TfL needed “to get back around the table, work together to resolve this dispute in the interests of passengers”.
The Mayor of London, Sir Sadiq Khan, said the strike action was “bad news for London”.
Sir Sadiq said he has encouraged the RMT to negotiate a settlement with TfL to end the strike.
“TfL have made clear they can’t afford its workers working fewer hours for more pay, but they are willing to talk to the RMT and other unions whenever there is a dispute and to try and resolve things amicably,” he said.
In Waterloo, central London, hundreds of people could be seen queueing up for buses.
BBC reporter Nicky Shiller said there were queues at all the bus stops he passed – and many of the buses were packed and had standing room only.
“I didn’t see any black cabs with the orange light on for hire. I think the cabbies will be having a very busy morning.”
