First things first: travel is FREE from 11.30pm on NYE to 4.30am the next day. This calls for a celebration! And thankfully there are tons of New Year's Eve and New Year's Day parties to attend, just make sure you can get to them and home again. Here's what's running when…
New Year's Eve
The underground will run a Saturday service all day and a handful of stations will either close early or have restricted access, so double check with TfL before heading out.
A Saturday service will operate and finish at the usual times on most of the line, except between Highbury & Islington and Crystal Palace/West Croydon and Camden Road and Stratford, which will both end around 2:50am.
The usual service will run on the DLR until 12:30am, when the wait between trains will extend to 15 minutes.
A Saturday service will operate on the buses, but be warned that numerous road closures for the fireworks will disrupt central London bus routes: Victoria Embankment, Whitehall, Millbank and Victoria Street will be closed from 2pm, while all of Westminster up to Marylebone Road and the Euston/King's Cross areas will be closed from 8pm until 6am the following day.
Ride anywhere but central, because those docking stations will be out of service until 1pm, January 2.
The Woolwich Ferry will run a one-ferry service, while the MBNA Thames Clippers run a varied service; visit @TfLRiver to get the low down.
New Year's Day
There'll be a Saturday service on all lines, except the Metropolitan, which will have a reduced service.
Saturday service pops up again on the Overground, except between Richmond and Willesden Junction and Romford and Upminster, which will be closed.
Expect a train every 15 minutes until 10am, when a Saturday service will take over.
Buses will run to a Saturday timetable, but routes that go through central London will be on diversion between 8am and 6pm for the New Year's Day Parade, which travels between Westminster and green Park.
Same as above, docking stations in the centre of the city will be out of service until 1pm, January 2
Same as NYE; a reduced service.
TfL will resume its usual service from January 2.
