List of bus routes in London

The numbering was revised in 1934 after London Transport was formed:[2] All routes operate in both directions unless detailed.

Route numbers from 900 to 999 represent mobility buses; these mostly provide a once-a-week return journey to a local shopping centre from relatively low-density neighbourhoods where there is no alternative route in the main bus network.

This is normally to provide a night service to destinations served by tube or train during the day.

These bus routes are not contracted to TfL and are therefore not 'London Buses', all but three run from villages and towns outside Greater London to destinations within.

They are painted in a colour chosen by the operator, so are not necessarily red like London Buses, and most of them do not accept Oyster cards.

Two double-decker buses on routes 8 and 205 at Bishopsgate in 2022
