For the EZ-track #4, #5, #6, and wye turnouts, how many degrees do the tracks diverge, and what radius are they?

Call me an idiot, but suppose I wanted to use Tidmouth sheds and turntable as part of a non-Thomas EZ-Track layout.  How long is the turntable bridge, and how long are the tracks inside the stalls?  Could the turntable and round house accomodate, say, a Spectrum 4-6-2, or a Berkshire like the Nickel Plate 765?  Certainly it could handle a Mogul or Consolidation, it looks like.

I have a couple questions.  How are these controlled?  Do they take up DCC addresses on the EZ Command?  Do they even work with the original EZ Command, or are they for the Dynamis?  If they work with the legacy EZ Command, where do they plug in/connect to the power pack?

Basically, tell me everything about them.
