That how I would do it anyway. When ever the street is divided in a way 
which prohibits cars to phiscally cross it (to U-turn or whatever), I 
split the road and have two seperate ways.
In case of a tram, station in the middle of the street; I would have 2 
highways and one tram-way. Between them, the stop/shelter can be inserted:

In my proposal i would tag it like the following:
have a railway=halt on the rails for each place a train may stop, for 
the platform I would tag the whole thing (usually a way) with 
railway=platform. All together goes into a relation as described earlier.

######a#############b######
===========================
######c#############d######

=== is tagged with railway=platform; ref=6,7; name=...
a would be railway=halt; ref=6a; ...
b would be railway=halt; ref=6b; ...
c would be railway=halt; ref=7a; ...
d would be railway=halt; ref=7b; ...

(again: Maybe amenity=platform would be more logical, but 
railway=platform exists, thats why I use it for now).

That way it can be rendered nicely and I can add either node "a" or "b" 
to my train route, and have a good grade of reality.
