One question though, can you use the narrow rail spacing around corners?
For some reason I think it should work, but I haven't had a chance to try it
yet.

I don't have any curves, but it wouldn't work exactly right.  If you think
of a 90° corner that goes up and turns right to form an 'r'.  Move the inner
rail two studs to the left.  Now, of course, it's two studs too short on the
exit at the top.  Move it two studs up, too, and again you're short.

I've thought of that problem, too.  I *think* it could be solved by building
a figure-8 track.  The outter tracks on each curve would be longer than the
inner tracks, but by having them opposite they would cancel each other out.

OK, time to dig out the 4.5volt track!!

That wouldn't work on its own.  Firstly you'd need a bridge, since a regular
crossing wouldn't be any use.  Secondly, there's no way you could keep the
tracks 2 studs apart around a 270° arc without lengthening the inner rail
somewhere.  Even a 90° arc needs the spacing to be spread out or it would
pinch too much at the apex.

(...) it (...) Not to mention the relative radii of the short & long rails would be wrong, so you'd end up with the rails wider apart at each joint than in the middle. This may not be enough to make it unusable, however, depending what wheels you (...) (22 years ago, 18-Mar-03, to lugnet.trains)
