Having decided to go DCC to simply the wiring and switching in the yard, a review of all of my loco stock reveals that this decision is a reasonable direction as all of my freight locos (GP-35, SD70, etc.) are readily upgrade-able to DCC with drop-in decoders. But alas, my passenger locos (F7, Mikado, etc.) are not upgrade-able to DCC! That realized leads me to adjust my DCC decision as follows.
A major decision made ...
As I close in on having to install all of the electrical wiring, I've made the decision to "simplify" my life by going with DCC. Some might argue the point about simplification but being certainly quite comfortable with digital computing, that side of things is likely a minimal challenge. The simplification of that I speak relates to the complexity of the wiring and block control switches that I would have to install on the Central End module.
