I'm starting to have some serious doubt's about Atlas' program. The only one I've ever used so far but after waking up getting dressed and going next door I stand there for about 20 minutes looking and really giving the room the eye ball. I look at a hand full of trains on my work desk and note how small they are to the size of the space I have available. My doubt about RTS is it isn't true to scale and meaning that isn't letting me get the full potential out of the space I have in a track plan. What other programs are there that might be more true to scale when drawing track on them?
