Thank you very much Ted for your input. It is genuinely appreciated.
When tossing this return to 3-rail idea around, my hope was to avail myself of more contemporary control.
Read: Some form of tethered walk around (or better yet, radio), but NOT command control. (I'm fine with utilizing block wiring.) The reason for wanting walk-around ability would be my desire to be able to walk about the layout as mood/situation inclines. (Such as switching/etc.)
Do you (or anyone) know if I would have options for walk-around conventional control of some type?
