I was going to ask how do you mark module boundaries, then I found the advice to use a rectangle shape (http://www.scarm.info/blog/tips-and-tricks/creating-layout-of-several-modules-in-scarm/) to do that. Instead, I'll just say in Kato-HO-UT the part S109B is pretty much the HO version of the Kato-N-UT B50C and that there's three more special purpose tracks for HO unitrack based on the S123, an uncoupler, a fixed ramp level crossing and a automatic signal.
