I have seen numerous streets where there are tram tracks in both directions, and the tracks are located in the driving lanes, not in a separate section down the middle of the street.</blockquote>
</div><br></div>As with any other railway, one way for each track, centered between the rails. That's the ground truth for railways. Remember, we have landuse=highway to disambiguate the situation if you want to highlight that the rails are in the highway area.</div>

The currently suggested key (as far as I know) is area:highway <a href="http://taginfo.openstreetmap.org/search?q=area%3Ahighway">http://taginfo.openstreetmap.org/search?q=area%3Ahighway</a> </div>
<div style><br></div><div style>To get the semantics right of trams in the street I guess you would for many cases need to use a lanes model which can then tell you in which lane the tram rails are (or between which lanes). Still in crossings stuff gets more complicated as tram lines tend to cross lanes because of different curve radiuses.</div>
