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).
