A broken lift doesn’t end a step-free trip.
For wheelchair users and people with buggies or luggage in London, on Android 16 with Material 3. Every day, lifts on London’s network fail, and a step-free filter hides the one thing that decides the trip. Level draws each route as the level changes along it and re-plans when a lift on the way stops.

To Tate Modern, with a lift out on the way.
The route drawn as a section. Street, ticket hall, platform: every lift is a change of level you can see.
A broken lift re-plans the trip. Southwark’s lift fails mid-journey; Level offers Waterloo with both lifts working.
Riders report back. One answer after arrival tells others whether the lifts worked.







Signage numerals and section drawings.
Switzer for every word and number, with numerals set like station signs, and every route drawn as a section through its stations. Material 3 on Android 16. A clickable prototype in HTML; the film above is recorded from it.
