Openptmap - Public Transport Map

Openptmap shows public transport lines. Depending on the zoom level, bus and tram lines are displayed in addition to the railway lines....

OpenPT Maps - London, UK with All available Public Transport Data overlaid.

Existing Features:

• Interactive Timetable function (timetables cover Europe)
• Zoom levels 4 - 17 (Large Scale Zooms)
• Line numbers

However, there are some useful new features also:

• Public transport network grid without background available
• Optional backgrounds: Mapnik and CycleMap
• Different background luminance (pale modes)
• Railway timetable on demand with mouse click (small squares)
• Aerial lifts are displayed

Openptmap editors can be useful in these situations:

• You added a new pt line to OSM and want to review it
• You want to get an overview of the Public Transport network without interfering background
• To find out the departure times of buses/trains at nearby stations
