It allows passengers to travel on select lines, making it easier for people to enjoy the nightlife in London without worrying about late-night transportation. Launched in 2016, the Night Tube runs on Friday and Saturday nights, covering key routes such as the Central Line, Victoria Line, Piccadilly Line, and others. This service aims to enhance accessibility and convenience for late-night travelers, supporting both residents and visitors in exploring the city after dark.
