More than 40 buses dating from 1908 to the present day formed up on Albert Embankment on Sunday morning to take part in a cavalcade as part of Transport for London's 'Year of the Bus'.
The buses were lined up on Albert Embankment before making their way up Lambeth Palace Road to Westminster Bridge en route to Regent Street where they were on public display for the day.
Buses ranged from a 1908 X-type Leyland bus to one of the Hydrogen-powered vehicles used on the RV1 as well as several of the 'New Routemaster' buses.
Leon Daniels, TfL's managing director of surface transport, said: "Buses have always been a key part of transport in London and this flagship Year of the Bus event will ensure that London buses, the bus drivers and the staff who support them get their richly deserved moment in the spotlight."
Forthcoming Year of the Bus events include an open day at Abellio London's Walworth Bus Garage near Camberwell Green on Saturday 19 July.
