Re: wiring

[Scott A Smiley <sc.smiley@juno.com>]

The only thing I would change is to bring the switch power plus 2
accessory powers.  This would give us flexibility to control other uses. 
You would not have to add a transformer as one can power both accessory
lines.

Everything else sounds great.  Good Luck with all this.  Looking forward
to seeing it.  If you need help let me know.

I will be trying to update some of the track on my modules, which is what
I think will address the pins, soldering  and ties.

Let me know when I can get the switch modules as I want to redo some of
the track and crossovers.  And work on the switches.
