Tracks are gonna' take up too much brick-countage, unless someone comes up with something better.
Actually, most modern tracks are curved
and angled, so trains can go faster over turns(actually, station was built on a turn which is kind of fail).

You see the track is curved and angled. That's actually not too modern, been around for awhile. Well.. back to the point, one screen(visibility distance in BL) of tracks will take thousands of bricks. So a better solution for less bricks first.
Trains are not that wide, that one is like 10.0ft(real information, don't remember length).
