Are there any web pages which have a study of how to line up Lego train
layouts with diagonal track?

That is, I want a little more freedom in my layout than forcing it to
always use ninety-degree curves and parallel/perpendicular tracks, but
I've found that if I try to be *too* freeform, nothing lines up and I
end up with two-inch gaps between the pieces I'm trying to connect.

If someone else has already done the math for how to make curves using
one, two, or three pieces of standard 22.5-degree curved track and then
get the track to line up properly and snap together firmly without
having to rely on any 'wiggle room,' that would be a great help to me!
Thanks!

If you're trying to keep things squared up, the two magic numbers are 7 and 11.

which is to say, a corner that keeps straights lined up with the normal Lego
geometry can be one of 3 things:

4 curves
1 curve, 11 straights, 3 curves
2 curves, 7 straights, 2 curves

There are similar combinations for coming off of switches, but they have the
same drawback as the corners: it takes lots of space.

thanks,

James

(...) This is very interesting... Is there a similar formula for a dog-leg? 1 curve, X straights, 1 curve the other way? What equations/formulae would you use to compute this? It's been way too many years since I studied trigonometry... --Bill. (22 years ago, 12-Nov-02, to lugnet.trains)

(...) The 1-11-3 design isn't very close at all, according to Track Designer. Here's what I did: straight, curve right, 11 straights (5 switches and a straight, but that is equivalent), 3 curves right, cross-track. Then from the cross-track, a bunch (...)
