The Victoria line is a London Underground line that runs between Brixton in south London and Walthamstow Central in the north-east, via the West End. It is printed in light blue on the Tube map and is one of the only two lines on the network to run completely underground, the other being the Waterloo & City line.

The line was constructed in the 1960s and was the first entirely new Underground line in London for 50 years. It was designed to reduce congestion on other lines, particularly the Piccadilly line and the Charing Cross branch of the Northern line.

All the stations have their own tile motifs

The depot is at Northumberland Park, the service and storage area for trains, is the only part of the Victoria line above ground. Trains access the depot via a branch line in a tunnel to the north of Seven Sisters.

The depot opened with the first stage of the line in September 1968. It is next to Northumberland Park railway station, on Tottenham Marshes in the London Borough of Haringey, over a mile from the Victoria line. When built, it was 900 feet (270 m) long and had working space for 22 eight-car trains. As part of Transport for London's tube upgrade scheme, the depot has been expanded and upgraded to accommodate all the 2009 Tube Stock trains.

This serves 16 stations and is 13 miles long.
