In August 1912 it was extended to Pimlico and has continued in that form until the present day, making this the oldest unchanged bus route in London.

[2] Thirty-three Daimler double-decker buses with 34 seats were allocated to route 24, now running between Pimlico and Hampstead, with the fleet name "British" painted in green livery.

[citation needed] During its life with London Transport, route 24 was operated mainly from Chalk Farm (CF) garage in Harmood Street.

[13] On 11 February 2008, a bus on diversion had its roof removed after the driver drove into the side rather than under the middle of an arch bridge.

[16] The Sun newspaper had to pay out £30,000 after allegedly misrepresenting the incidents, stating that the driver was a fanatic who had forced passengers off the bus.

[21] In March 2022, the route was digitally recreated and released as an addon for the bus driving simulating game, OMSI 2.
