These parameters can be configured on the panel in the top-left. The travel duration is capped at 120 minutes.</p> <p> Between stations Fastreach considers walking as well as trains, trams and busses according to their timetables. The reachable area is visualized via a multi-polygon. It’s properties are described in the top-right panel.</p> <p> Fastreach uses the weekly timetable data provided by Delfi e.V. from the 15 September 2025. Accordingly, timetables can only be considered complete from 15 September to 21 September. Data for walkways is taken from OpenStreetMap. Fastreach’s source code lives on GitHub.</p> <p> No personal information is processed on this site. For the map tiles your browser makes requests to OpenStreetMap.
