The 100th anniversary of the roundel was celebrated by TfL commissioning 100 artists to produce works that celebrate the design.

The Greater London Authority, a replacement authority for the GLC, was set up in 2000 with a transport executive called Transport for London ( TfL ) that took control from 3 July 2000.

The London Underground did not pass to TfL until after a Private Finance Initiative ( PFI ) agreement for maintenance was completed in 2003.

The first Commissioner of TfL was Bob Kiley.

On 1 June 2008, the drinking of alcoholic beverages was banned on Tube and London Overground trains, buses, trams, Docklands Light Railway and all stations operated by TfL across London but not those operated by other rail companies.

Carrying open containers of alcohol was also banned on public transport operated by TfL.

This proposed scheme was highly controversial and resulted in strong differences in opinion between TfL, who supported the scheme, and local councils throughout the proposed route, who all took a ' no tram ' stance.

The proposed West London Tram was postponed indefinitely by TfL in August 2007 after it was announced that the Crossrail project would be going ahead.

In 2006, the last year before the zone was expanded, TfL observed that traffic flows were lower than in any recent year, while network traffic speeds were also lower than in any recent year.

TfL applied for planning permission and listed building consent for providing access to platforms 5 and 6 on 1 October 2008, but the application was subsequently withdrawn.

This decision to end the counterflow was made despite a 2006 independent report, commissioned by TfL, which concluded that " the proportion of accidents occurring in and around tidal flow operations is not significantly higher than would normally be expected on this type of road " and which recommended that " accident mitigation should be focused in the first instance on speed management aspects, and specifically on the deficiencies, limitations, and in some cases, inconsistencies in the signing, signalling and road marking regime ".

In 2009, because of financial constraints, TfL decided to stop work on a project to provide step-free access at Osterley on the grounds that it was a relatively quiet station and within one or two stops of an existing step-free station, Hounslow East where step-free access has been available since 2005.

The station building still exists and was put up for sale by TfL in February 2010.

A replacement London Victoria to Bellingham service was mooted by previous mayor Ken Livingstone, but funds for this were transferred by current mayor Boris Johnson and TfL to pay for the East London Line extension to Clapham Junction.

The Oyster card was set up under a Private Finance Initiative ( PFI ) contract between TfL and TranSys, a consortium of suppliers that included EDS and Cubic Transportation Systems ( responsible for day-to-day management ) and Fujitsu and WS Atkins ( shareholders with no active involvement ).

TfL stated that the contractual break was to reduce costs, not connected to the system failures.

In November 2008, a new contract was announced between TfL and Cubic and EDS for two of the original consortium shareholders to run the system from 2010 until 2013.

The Oyster name was agreed after a lengthy period of research managed by TranSys and agreed by TfL.

Although the RFID chips were charged in the normal way and no fare evasion was involved, TfL disapproved of the practice and threatened to fine anyone not carrying a full, undamaged card.

TfL said this was due to the administrative and environmental costs of customers disposing of Oyster cards instead of re-using them.

Both routes were transferred to standard TfL contract ; the 353 was withdrawn between Addington Village and Croydon, and the 354 ( renumbered T33 to reflect its new status as a Tramlink ' feeder ' route ) was withdrawn between Addington and Bromley.

The background to this purchase relates to the requirement that TfL ( who took over from London Regional Transport in 2000 ) compensates TCL for the consequences of any changes to the fares and ticketing policy introduced since 1996.
