Hi Dale,
Thanks for the compliment on the wiring. I'm trying to emulate Mike CT on the wiring front, plus there are some EEs at work who do outstanding wiring work. If I ever want to invite them to see the layout, I've got to keep up! ;^)
Not sure I understood your comment regarding mixing of transformers. And I was probably unclear in my previous comment.
The western panel holds the terminal strip pairs for districts 1, 4, 5, 7. The eastern panel holds the terminal strip pairs for districts 2, 3, 6, and 8.
Districts 1-4 which form the main loop and the passing siding (see Blue, Lt Green, Red, and Magenta track segments in Photo 2) are powered by two 180 watt Lionel PowerHouse transformers. These districts also have the TPC-400 in the circuit so that conventional locomotives can be operated there.
Districts 5-8 are yards and spurs and are powered by both sides of an MTH Z-4000. I tend to move the handles to 15 volts, which mates up with the command setting of "Low" for the TPC (been awhile since I played with these settings). Thus far, I haven't experienced any locomotives going into "rocket assist" mode as they cross from the Lionel / MTH boundary.
Hope that was clearer. Thanks for looking!
George
