Please note: The situation is continually changing and the Metropolitan Police have advised that all passengers check that the services they require are running before they attempt to travel.
Public transport across London has been severely disrupted by a series of explosions in the city today. The entire London Underground network has been shut down and there are no buses in central London. Mainline trains have also been affected, as have airport services and roads.
Buses
There are currently no bus services running in zone one in central London. Extra safety checks are being carried out on all buses that remain in service and at all bus garages after an explosion that ripped through a bus in Tavistock Square.
London Underground
The entire tube network has been suspended until further notice, as has the Docklands Light Railway.
Trains
All stations except King's Cross have reopened, though a spokesperson for Network Rail advised that services will be reduced and subject to delays.
The Heathrow Express, which runs from Paddington station in west London to the airport, has resumed service. The Stansted Express was not travelling as far as its normal terminus at Liverpool Street station. The Gatwick Express has been suspended.
The London to Paris and Brussels Channel Tunnel high-speed train company Eurostar was continuing services into and out of Waterloo station in the capital. However, a Eurostar spokesperson said that they are "advising passengers on the continent not to travel to London" and that full refunds will be offered to those who choose not to travel.
London to Scotland train company GNER said it did not expect any of its East Coast main line trains to be able to get in and out of London today and that services were likely to get only as far south as Peterborough and Stevenage. Train companies advised passengers not to try coming into London today. Among other train companies unable to run all the way into London were First Great Western and Silverlink. First Great Western trains ran only as far as Reading, Berkshire.
Airports
Airports are open at the moment, though passengers are advised to contact their airlines or travel operators for more information, and to bear in mind that the Metropolitan Police has advised against all non-emergency travel in London.
The Federation of Tour Operators (FTO) advised passengers due to fly from London area airports to go to the airport to check in, even if the disruption to public transport meant they were delayed in arriving. The FTO said: "If customers miss their flight as a result of the incidents, FTO members will endeavour to source seats on alternative flights operated by or on behalf of members."
Roads
The Highways Agency says there are signs on all major motorways into London advising drivers to avoid the capital. The M25 is said to be running smoothly at the moment, but a spokesperson for the Highways Agency said that they expect the motorway and all routes out of London to be busy this evening.
An RAC spokesman said: "Once people heard news of the explosions, some tried to leave London. The roads in the centre are totally gridlocked and we are warning people not to drive in the London area.
"Our advice to people who feel like leaving offices and trying to go home at the moment is to stay put and listen to advice from the police and emergency services."
