Dave said:Also, aren't all trains wider than the tracks anyway? Otherwise you'd be able to touch the track and bogeys?
Most (almost all modern coasters, I can't think of any still being built that aren't), but, many of the old Vekomas and Arrows have track wider than the trains, Corkscrew and Loch Ness Monster proves this on RCDB. That's why you can see the wheel covers with a big "DON'T STEP HERE" on them.
Also, the Togo pipeline coasters and Bobsleds definitely aren't .
