The Night Tube is a service pattern on the London Underground system which provides night-time services to travellers on Friday and Saturday nights on the Central, Jubilee, Northern, Piccadilly and Victoria lines.
Since the London Underground's inception, the practice of running night-time services has been difficult, mainly due to night-time noise factors, and the ongoing maintenance works that usually occur during the night. General mass upgrades to the overall London Underground network from the late-1990s onwards, along with large infrastructure improvements to stations and signalling, plus the building of Crossrail (with the future probability of Crossrail 2) which will have sections going underground to connect with the main London Underground system, made it possible to introduce a limited night-time Tube service.
The Bakerloo, Waterloo & City and sub-surface lines have yet to be upgraded and re-signalled, but it is expected that when these works are completed on these lines, they will also have 24-hour services. Part of the London Overground (Highbury and Islington to New Cross) should begin Night Tube service by 2017, while the sub-surface lines and Docklands Light Railway are planned to begin Night Tube services in 2021.
