OK, using Stan’s 2 points as an orgazing principle for this discussion.
I understand the need for some kind of triggering device. If placed on the circle of the dogleg before the track joins the down hill run I guess that could work. I’d have to program the O22 switch so it always returned to the first position so the that on its way back up the grade the train doesn’t hit that trigger while the consist is still coming uphill.
But the whole discussion of Doods and rectifiers in #1 and the attached string is way beyond my experience or understanding. You’ll need to take me back to first grade on that.
I have figured out how to reduce my grades slightly. Two of my locomotives do have magnatraction.
thanks for help with this.
