openptmap shows public transport lines. Depending on the zoom level, bus and tram lines are displayed in addition to the railway lines. Link to the map: http://openptmap.org.
Motivation and Purpose
Between autumn 2010 and spring 2011 due to hardware problems the very advanced and commonly used Openbusmap had not been fully available any more (unavailable tiles, no data updates). For this reason the author of openptmap was searching for a temporary replacement and finally programmed a simple Slippy Map which shows different means of public transport in different colors. These are the limitations in comparison to Openbusmap:
- just one interactive function (timetable link for Europe)
- limited to zoom levels 4 - 17
- line numbers are attached to the lines in an unordered manner
However, there are some useful new features also:
- public transport network grid without background available
- optional backgrounds: Mapnik and CycleMap
- different background luminances
- DB railway timetable per mouse click (from zoom 15) - basis: uic_ref, ref_name, name
- aerial lifts are displayed
- there is no rendering on request, i.e. you need not to wait for rarely accessed tiles to be rendered
Despite the limitations, the openptmap 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 pt network without interfering background
- to find out the departure times of buses/trains at nearby stations
Color Meaning Tag Deprecated Tag black railway route=train line=rail green S-Bahn route=light_rail

Station Names in OSM Database
In general, the name=* tag is used. For the links to Deutsche Bahn timetables, the uic_ref=* tag is preferred. Bus and tram stations usually do not have a uic number, but they can be identified by the station name, followed by the city name. Example: ref_name=Steintor, Hannover
The map is updated approximately every other day. Hence you can expect new edits to be displayed within 1 to 4 days. There are no updates on the fly, that means, every tile of the public transport layer can be accessed directly because it has already been rendered.
