There are lines in Karlsruhe which use only the tram current (750 Volt DC), e.g. line S1 from Hochstetten via Karlsruhe to Bad Herrenalb. This line shares tracks with freight trains between Lepoldshafen Frankfurter Straße and Welschneureuter Straße. That's similar to the train track in Waterloo. >> Tag the tracks as they look like.

It does not share the space but according to your photos at Twitter the trackbed seems to be paved and cars could use it. A proper light rail has either ballast or grass between the tracks, i.e. car drivers will recognize that the cannot use this space. https://www.mapillary.com/map/im/jx4Z1BdL_nhENDjJMxHI2w http://www.regum.de/en/rail_products/lawn_track There is no sharp border between trams and light rails.

If the track is still usable for freight trains (even if limited to certain hours), it is a normal railway track and therefore gets railway=rail. What you describe is called "Karlsuhe model" – don't confuse it with our tagging scheme at OSM. ;-) I assume, that some people of Grand River Transit have visited the German cities Karlsruhe and/or Kassel. :-) The first one has been operating a tram-train system for more than 40 years. https://en.wikipedia.org/wiki/Karlsruhe_Stadtbahn https://en.wikipedia.org/wiki/Kassel_RegioTram Tag the tracks as they look like.

[Talk-ca] Light rail mapping questions
Hello Waterloo Region is in the process of building a light rail system. This has meant a lot of streets are being reconstructed and changed, and now that large portions of the line are completed, there are lots of changes that will need to be made to map what is the largest infrastructure project local governments here have undertaken. There are similarities to some other Canadian light rail and streetcar systems (with dedicated rights of way), but also some unique features which I'd like to get some advice about how to map. Along on-road sections, the dedicated rail right-of-way moves from centre-running to the outsides of the street at certain intersections. (A by-product of some of the political compromises in route choices.) Does anyone know of any examples of tracks going from the centre to the side of the road with traffic lanes in OSM? I expect these are going to look messy. There are also portions of the line that will share track with a freight corridor. From what I can tell, convention appears to be to tag it with the heavier mode, i.e. railway=rail instead of railway=light_rail. However, the use of the track for freight is quite small - at most one freight train to/from Elmira uses the track at night, when light rail service won't be operating. Should the track still be marked as 'rail' instead of 'light_rail,' or should we attempt to have the tags represent the dominant use? (At present, some of these are tagged as railway=construction, even though the freight train has been consistently using it overnight. This section is also largely complete.) Further, there is gauntlet track to allow freight trains to pass station platforms. Do we tag the track closest to the platform as railway=light_rail and the outer track as railway=rail? There's some discussion here on gauntlet tracks here that suggests this is the case in Europe: http://forum.openstreetmap.org/viewtopic.php?id=29131 Thanks Mike -- Mike Boos ___ Talk-ca mailing list Talk-ca@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-ca
