I'm sure you've come across those big loop which railways use to gain height within a limited area (what do you call them?). I've been using a few on my mountainous line and was wondering how do those professionals, or at least the more experienced Trainzers, get about to creating them. I lay all my loops by eye, and they often turn out with uneven grades and extremely inconsistent curves.
Anyone has tips? =)
