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.

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.

There is no sharp border between trams and light rails.

I would use different tags but the ideas is similar.

The right/back of the photo:
lanes = 4
lanes:forward = 2
lanes:backward = 2
access:lanes:forward=no|yes
access:lanes:backward=no|yes
tram:lanes:forward = yes|no
tram:lanes:backward = yes|no

The left of the photo:
lanes = 4
lanes:forward = 2
lanes:backward = 1
turn:lanes:forward=
tram:lanes:backward = no|yes
access:lanes:backward = yes |no

Differences to James' suggestion:
My suggestion is compatible with the widely used lanes tagging scheme. I
used "backward", not "backwards" (see Taginfo). I used "tram", not "train".

Best regards

Michael

Here's an example of an intersection that's largely complete:

The tracks on the right/behind of most of the photos are centre-running

lies between the sidewalk and the roadway. (The other track branches off

I don't know if I'd characterize this as a "Karlsuhe model" train-tram -
the system is entirely within a single urban area (even if it does span two
adjacent cities), it just uses an existing rail corridor in some places.
Unlike the Karlsuhe system, the vehicles have only a single operating
voltage.

I don't know if I'd characterize this as a "Karlsuhe model" train-tram -
the system is entirely within a single urban area (even if it does span two
adjacent cities), it just uses an existing rail corridor in some places.
Unlike the Karlsuhe system, the vehicles have only a single operating
voltage.

Look at any German, Austrian or Swiss city of your choice where every
tram track is mapped as a single way in OSM (i.e. no tracks=2). I need
more details (show us photos) to give a useful answer.

Yes. 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. Sections where tracks share space with
cars [1] are railway=tram. Where the trams are physically separated from
the traffic [2], it's a railway=light_rail. That's how tagging works in
cities which only have *one* tram/light rail system. If the city has two
or three (low-floor tram and high-floor light rail; some German cities),
it becomes more difficult because we also try to get the systems
distinguishable (there are use cases). But that is not important now and
the reason why Germans discuss correct tagging of trams, light rails and
subways at their OSM Forum over multiple pages and threads. :-)

It is the case in Kaufungen near the city of Kassel which has a
Karlsruhe-like tram-train system ("Regiotram").

https://commons.wikimedia.org/wiki/File:Haltestelle_Niederkaufungen_Mitte_02.JPG

Yes, the track for heavy trains is a normal train track (railway=rail)
while the outer ones can only be used by light rail vehicles due to the
smaller structure gauge. Therefore the light rail track gets
railway=light_rail. Because we map one way per track at the centerline
of the track, there are two (in Kaufungen three) parallel tracks and all
get railway:interlaced=yes. This is useful for routing engines.

If there were up to date Mapillary photos, I could give more and better
advice. (Mapillary photos by pedestrians are better because are located
on the sidewalk)

[Talk-ca] Light rail mapping questions

2016-10-17 Thread Mike Boos
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
