Hello,
for the purpose of calculating average speed on streetcar routes by
section, I need to extract the kilometration of the lines, including
stops of course.
What I do not mean is to take a tool à la Google Earth's "path" tool
and re-trace the routes myself, since the vector paths are *already* in
the map.
Is there any way to do this?
TIA,
Sincerely,
Wolfgang

in a first step you could take a planet file and filter out only the
objects you need. Then you could import the filtered data into a
database, e.g. with osm2pgsql. With a PostGIS database you are able to
do many different geographic queries such as getting all nodes that are
part of a way or calculating way lengths.

Thanks for that. In that case I'll stick with the "path" tool in Google
Earth though.
I had just hoped that someone would have actually thought of
implementing a user interface for extracting information from
Openrailwaymap. But, well, "web application" and "user interface",
those two things just don't seem to fit.

the website is still in an early development stage, so there are a lot
of features that are planned, but not realized so far.
But as well as OpenStreetMap, the main focus of the project is to
collect free data, not to develop every possible application for free.
And as well as the osm.org website, openrailwaymap.org is just a kind of
showcase to present possible usecases of the collected data to attract
other developers.
We spending our freetime for this project and get not enough donations
to pay the server rents without using our own money. And we have not
enough time to implement all user wishes. If someone wants a special
feature, he could either develop an own application, or he contributes
to the project by coding or donations.
Sorry for these words, but it is not really motivating when users just
send feature wishes, but do not support us to realize them...
