Thanks for the feedback folks... it's been a while since I posted the original question but I still haven't bought my needed track and roadbed to complete my layout. It's been a busy summer :)
I'm looking for a good place to get Atlas flex track and Midwest cork for N scale online. I know I ran across a thread once that suggested some inexpensive vendors, but I've lost that. Does anyone have any recommendations?
Just an observation about the size of Z as opposed to N...
Remember for instance that N is roughly 1/2 the size of HO, right? This means that the total cubic volume of the equipment is roughly 1/8 the size of the same piece of equipment in HO.
The same carries over to Z with respect to N...
