Commuters faced long queues at Harrow-on-the-Hill station on the Metropolitan line today as the first morning of a 48-hour Tube strike got underway.
Transport for London said its ambassadors will help keep Tube stations open and passengers on the move during the 48-hour walkout by London Underground workers.
TfL said a record 7,961 buses were running in London after 266 were added to the service.

London Overground services will be unaffected by strike action but trains and platforms are expected to be far busier than usual, TfL has said.
Strike update- London Overground services are not expected to be affected by industrial action, but will be much busier than usual.
Eurostar has had to cancel six trains today - two from London to Paris, two from Paris to London, one from London to Brussels and one from Brussels to London.
The Channel Tunnel trouble came as millions took to the roads at the start of the holiday, with the weekend likely to see as many as 16 million cars on the move.
Two separate incidents have led to hours-long delays to those taking Folkestone-Calais shuttle trains and high-speed Eurostar services between London and Paris and Brussels via the tunnel.
The first problem came earlier today when a fatality near Lille in northern France involving a French high-speed train resulted in diversions and delays to Eurostar trains.
Then, just as Eurostar services were getting back to normal, a Eurotunnel passenger shuttle train broke down in the tunnel leading to further delays to Eurostar services and long hold-ups of up to four hours for shuttle-train passengers.
The Government has announced a £600 million compensation scheme for homes and businesses affected by the new HS2 rail line that will pass through Buckinghamshire and Oxfordshire.
The Government insists it is one of the most generous packages of its kind. It has been revealed that 532 properties and businesses will be demolished. Residents have already reacted saying the plan is "an insult."
Those living within 60 metres of the line will get the full value of the property and 10 per cent on top - up to £47,000 maximum.
Those between 60-120 metres will be able to get the market rate of their properties or a cash payment of between £30,000 and £100,000 if they decide to stay put.
And for people living 120 and 300 metres from the route there will be compensation payments of between £7,500 and £22,500.
Our Transport Correspondent Mike Pearse has been gauging the public reaction to today's announcement.
