I am just starting to think about abandoning my HO stuff, most of which is still in their boxes in favor of On30. My layout room consists of most, but not all of, a 12' x 13' bedroom. I have to leave aisle access to the closets, and to get to my workbench, in a dormered alcove. My question is, do I have room to do such a layout that would be more than an along-the-wall switching layout? I enjoy switching industries. I've discovered that O-scale buildings are significantly larger than their equivalent HO scale building. So I have to be convinced that I have enough room. I briefly considerred Sn3 but that looks like too much work kit bashing or scratch building pretty much everything, unless you can afford brass. I cannot. The reason I am considering abandoning HO is that the On30 equipment from Bachmann runs so much better than the equivalent in HO scale.
