Reply to "SCARM Layout"

Your layout is a good size and I like your design. But I have several suggestions.

1. Save all the O36 for the railyard only.
2. Make O48 your minimum radius for the mainline.
3. There are three O36 "S" curves on the mainline (counting the siding). Try to make O72 (or larger) the minimum for all "S" curves on the mainline.
4. When possible, allow one car length of straight track in the middle of an "S" curve.
5. There is a single reverse loop so you can reverse the direction once. Then if you want to reverse again, you must back the train through the wye. There is nothing wrong with this, in fact it is great that you have that wye. But you should be aware since this will affect the way you operate.
