You need to determine the railway value from the track infrastructure.
In Karlsruhe (Germany) the tram has the same gauge as the rail and even
runs on normal rails in some parts where in the city it is a simple tram.

Living in a very detailed mapped city with tram lines (mapped per track)
and even highway intersections falsely mapped per (turn-)lanes, I pretty
aware of the problems.

For railways these problems are only with trams (e.g. directly
interacting with highways) except of crossings, and this problem is
connected to the separate tagging of footways and other lanes. Railways
normally are barriers which often are forbidden by law to cross but tram
rails on a road are totally different.

Using a relation for intersections/crossing, the only problem with the
current tagging scheme would be with trams and the major concern is
loosing the details (see
http://lists.openstreetmap.org/pipermail/talk-de/2013-March/101172.html).

For me the easiest way would be to map highways per lanes and invent new
tags for a street as whole which I could cross without problems (eg. we
are inconsistant there too as one metre of grass is not really a barrier
for me). This will probably never happen though.

That is where I stumbled over this problem, too.

I did try to clean up some of the highways representing lanes but what
to do with the separately mapped tracks and sidewalks ?
