Talking T Gauge

As the guy who asked about the wheelsets in the first place, giving rise to the tech spec at:

http://www.t-gauge.net/tech.htm

I'd like to ask a couple of supplementaries. I wasn't worried at the time, but I'm toying with a little piece of design work (see below) and now these things will prevent me re-inventing the wheel.

The quoted radii: can someone confirm that these are to the centreline (if such a thing is meaningful in three mil gauge)?

and, to save me having to work it out, if you build a double oval as per what I believe is the promotional pack, what's the centre to centre spacing between the parallel straight tracks.

...

Errm, Andy, why are you interested?

Well, Peter proposed Nn18 in what is now the Narrow Gauge forum, at about the same time as I did on the Gn15 list, so I moseyed on here to play. He's now posted his layout idea on his blog/website. The idea of a sector-plate and traverser reminded me of an experiment on the Gnatterbox a while ago.

John Baxter started a discussion of swivelling turnouts (ones without frogs), and about five posts down that thread is a nifty crossing thing, not actually a full-sized prototype, but from a 5" gauge line. I liked it a lot, and after a dispiriting night working on what was then my main layout, figured out how to build one from standard components.

Now, Peter's design, although he intends the town trackage to be 'mainly cosmetic', set me to thinking that I might, instead of a diorama, build a tiny layout based around one of these, hidden in some trees or something, which would mean I didn't have to build points/turnouts, which is clearly going to be well beyond my capabilities.

Which is why the questions.
