O27 and S Gauge - Classic Toy Trains Magazine

Hello, all. I'm new to the Forum. I'm sure you've heard every gauge question imaginable, but here goes...

I've got some space in my attic for a fair-sized layout. But with walls pitched at 45 degrees and the need to do an around-the-walls layout, space is a little tight. But every time I consider HO, get a feeling like I know that's not where my heart is.

I've got a bunch of o27 stuff from 20 years ago. With a little TLC, it should be up to snuff. In addition, I'm very impressed with some of my brother's new o-scale, but I don't think I could bring myself to plunk down the cash. So I'm thinking just settle on o27, though it is not to scale, and buy o-scale in the future.

But I'm wondering about the viability of running o27 on S-gauge trucks and track. Also, what are your opinions about S gauge in general? is it scale? Would it be scale or near scale to run o27 on S track?

Thanks for any advice you can give.
