It takes time, but my tracks are straight where I want them straight, and nice, graceful curves where I want/need them curved. I'm using "gates" from the wall category to make supports I can live with. I also place a station anywhere I place a switch to assure my trains make it thru the switch unbroken. Doingit nice means building some extra stuff, and tearing it back down. I consider it scaffolding, and have never seen much of anything built without using that in some way. Get creative.
