About 200 million passengers a year use the Victoria line.
It is the sixth-most heavily used line on the network in absolute figures, but in terms of the average number of journeys per mile it is by far the most intensively used.
From May 2017, trains run every 100 seconds during peak periods, providing 36 trains per hour.
All trains run from Brixton to Seven Sisters and some continue to Walthamstow Central.

When the line opened, services were operated by a fleet of ​39 ¹⁄₂ eight-car trains of 1967 Tube Stock trains.
In the early planning stages, an articulated type of rolling stock was considered, but not progressed because of difficulties transferring the stock to Acton Works for heavy overhauls.
After Acton Works closed this no longer applies.
The 2009 tube stock has a wider profile and slightly longer carriages which precludes it from running on other deep-level tube lines.
The 1967 stock was supplemented by 1972 Mark I Tube Stock, transferred from the Northern line and converted to be compatible with the 1967 stock.

Replacement of the 1967 rolling stock began in July 2009.
The 2009 Tube Stock fleet of 47 eight-car trains, was built by Bombardier Transportation.
Testing the first prototypes began in 2008.
The trains began to be introduced in 2009 and most were in operation by the following year.
The last of the 1967 stock trains ran on 30 June 2011, after which the entire service was provided by 2009 stock.

On opening, the line was equipped with a fixed-block Automatic Train Operation system (ATO).
The train operator closed the train doors and pressed a pair of "start" buttons and, if the way ahead was clear, the ATO drives the train at a safe speed to the next station.
At any point, the driver could switch to manual control if the ATO failed.
The system, which operated until 2012, made the Victoria line the world's first full-scale automatic railway.

The Victoria line runs faster trains than other Underground lines because it has fewer stops, ATO running and modern design.
Train speeds can reach up to 50 miles per hour (80 km/h).
A popular way for locals in north London to visit the West End is to take the Northern line to Bank, change platforms at Euston, and continue on faster Victoria line trains.
The original signalling has been replaced with a more modern ATO system from Westinghouse Rail Systems incorporating 'Distance to Go Radio' and more than 400 track circuits.
The track operator, London Underground Limited, claimed it is the world's first ATO-on-ATO upgrade.
The new system allowed a revised timetable to be introduced in February 2013, allowing up to 33 trains per hour instead of 27.
In combination with new, faster trains, the line's capacity increased by 21%, equivalent to an extra 10,000 passengers per hour.
