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.

| (...) 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. (21 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 (...)
