London Buses route 23

Running between Westbourne Park station and Aldwych, it is operated by RATP Dev Transit London.

On 14 November 2003, Alexander ALX400 bodied Dennis Trident 2s replaced the AEC Routemasters that had operated it since its inception.

[4] On 5 January 2009, a bus operating on the route crashed into a shop in Westbourne Grove after swerving to avoid a van, injuring ten people.

[5] Later in 2009, Transport for London decided not to proceed with a possible change of the eastbound route in the Elgin Crescent area, following a consultation with residents and local interest groups.

[13][14] On 23 November 2022, it was announced that a proposed rerouting of route 23 at Hyde Park Corner to serve its previous terminus of Aldwych instead of Hammersmith, only now via Green Park, Piccadilly Circus and Trafalgar Square, would be going ahead following a consultation; it was implemented on 29 April 2023.
