(1) No. Jumpers inside the track switch carry track power to all the center rails. Thus track power (the variable voltage being generated by the Z-1000 throttle) is fed from the center rails of track pieces adjacent to the track switch. Accessory 14VAC is only fed to the switch motor and the switch lantern, completely separate from track power.
(2) Same answer, really. Power is fed to the center rails by inside jumpers.
