Step-free access stations have lifts or ramps - or a combination of both - so that customers don't have to use escalators or stairs to move between the street and the platform.
There are currently 70 Tube stations and 57 London Overground stations with step-free access. All DLR stations are step-free.
Lifts or ramps will be built to provide step-free access at several other stations during the next ten years:2016/17: Ealing Broadway, Tottenham Court Road
Step-free access projects don't always create level access between the platform and the train. But any new trains introduced as part of our work to improve the Tube should minimise the step and gap between platform and train.
In some places we are also providing portable ramps that can be positioned by station staff or building platform humps - permanently raised areas on the platform.
