One idea another OSMer suggested a while back (when the idea of tagging tracks still sounded ridiculous) is to have some way of distinguishing between a 'track' and a railway line (or 'corridor' is perhaps a better word), so that renderers can choose which to display (and so that the data contains both conceptually different things). Not sure how best to implement this. The easiest thing would be to have the middle track double up as the way which represents the line, somehow. The hardest thing might be to have ways which mark both edges of the rail corridor (like how we do riverbanks).
