Ken - To add to my previous post, I like all those layouts you posted. Do you have those plans without labeled tracks or possibly a parts list? The other thing is, it will be a while before I can complete a full layout due to the prohibitive costs of those switches. So one thing I like are layouts that are able to be built in stages. I will start with an outer loop then work my way in buying a switch here and there.
Are there any track pieces that can be substituted in for a 0-48 switch temporarily? Will a 10" piece of fastrack fit the straight side and a curved 0-48 piece if the switch is on a curve?
