The London Night Bus network is a series of night bus routes that serve Greater London. Services broadly operate between the hours of 23:00 and 06:00.
Many services commence from or operate via Trafalgar Square and are extensions or variations of daytime routes and hence derive their number from these; for example, route N73 from Oxford Circus to Walthamstow Central follows that of route 73 as far as Stoke Newington, before continuing further north.[1][2][3]
History
The first night bus was introduced in 1913.[4] By 1920 there were two 'All Night Bus Services' in operation named the 94 and 94a running from 23:30 to 05:30.[5] A few more services were introduced over the following decades, but all ceased during World War II. Services resumed after the war, increasing as trams and trolleybuses were replaced in the late 1950s and 1960s. In 1978 London Transport listed 21 all-night bus routes. On many of these routes, "all-night" service meant a departure frequency of no more than one bus an hour.[6] In April 1984, the number of routes was increased from 21 to 32. At this point the peak service required 80 buses; by August 2013 this had grown to 890.[7]
Originally the night bus network had its own fare structure, but with the introduction of the Oyster card in 2003, it was incorporated into the Transport for London fare structure. Until the mid-2000s, all routes had N prefixes. However, as some routes merely mirrored their day time equivalents, the N prefixes were dropped and these routes became 24-hour services; for example, route N14 was no longer differentiated from route 14.[7]
Services are operated by private operators under contract to London Buses. The Night Bus contracts are often bundled with those of the equivalent daytime routes and awarded for a five-year period, with an optional two-year extension based on performance standards being met. Some however are tendered individually.[7][8][9]
With some London Underground lines operating a 24-hour service at weekends from August 2016, a further eight routes commenced 24-hour operation on Friday and Saturday nights.[10] Further changes were made as the Night Tube network expanded.
In May 2015, the Night Bus network was the subject of The Night Bus, a Channel 4 documentary.[11][12]
Operation
Night Bus routes are often related to the day numerical equivalent, normally running the same route but with an extension at either end of the service. This is normally to provide a night service to destinations served by tube or train during the day.
However, there are a few N-prefixed route numbers that have no relation to their daytime equivalents: the N5, N20, and N97 all operate in a different part of London to their respective day routes. Also, the N550 and N551 (which provide night service on parts of the DLR network), and the N271 (whose daytime service was withdrawn on 4 February 2023) have no corresponding daytime routes.
There are also 24-hour routes, which run day and night but usually with a lower frequency during the night hours. The vast majority run the same route at all times. With the introduction of the Night Tube, some day routes have been extended to run during Friday and Saturday nights to serve the stations.
