A couple of questions if I may.

1) Do the EZ track turnouts (Part #44131 and 44130) have internal switch motors like kato uni track or can I use tortois or similar?
2) If they have internal how do I hook them up to an NCE Power Cab system? Do I still need a controller, and if so which NCE controller do I need the "switch it" for slow motion or the "snap it" for twin coil

I need to know what the defacto standard is for tunnel portal width and height for On30 and what is the center to center parellel track spacing when using HO Scale EZ Track?
