After having taken down my floor layout a year or two ago I've finally built a train table and am getting back to wiring the layout. I've revisited a couple books on track wiring and DCS, but am hoping someone can clarify a few questions I have regarding MTH Realtrax switches which will all be hooked up using auxiliary power (the 14v accessory power on the MTH z1000 power brick).
1. (also 1 in the image) - With a switch on each side of this piece of track does the track need its own connection to track power?
2. (also 2 in the image) - Where does an engine whose rollers will be on both switches (as you can see two switches are connected together) for a short period of time get its power? Does an engine use the 14v power going to the switch to keep moving in this case or somehow use the 18v from the connecting track? Is there another explanation? Thank you.
