London Buses route N68

London Buses route N68 was introduced in the 1970s, and ran between Wandsworth (Armoury Way) and Farringdon Street via Clapham Junction, Lavender Hill, Vauxhall, Millbank, Parliament Square, Trafalgar Square and Aldwych. It replaced the night service on route 168, and was the last night route to be introduced before the major enhancement of the night bus network during the 1980s, when a great many more routes were introduced. The N68 had the meal relief journeys to Liverpool Street “livened up” in 1975, and was diverted to run via Strand and Aldwych instead of Victoria Embankment during the 1970s. London Buses route N68 was replaced by route N77 and N44 (running between Vauxhall and Aldwych).

Today's London Buses route N68 was introduced in 1995, linking between Trafalgar Square and Purley. It was withdrawn between Purley and South Croydon; and also diverted to Tottenham Court Road on 28 April 2000. It was transferred to London Central in 31 March 2006.
