Analog loop reversing relay

[Dave K]

I do not have DCC. I have simple analog DC.

Considering all of the polarity changes, should I consider using the "common rail system"?

why would you think common rail would improve things because of all the polarity changes?

each reversing section requires gaps on both rails at its boundaries which implies the mainline has gaps in both rails at its boundaries.   there's no rails in common between the mainline and reversing sections.

 

if you use multiple throttles, there must be switches to connect at least one rail from a block to just one throttle.

both rails of a reversing section must be switched between each throttle along with a DPDT reversing switch.

Somewhere in this thread or the other thread, I carefully described how to wire the whole thing for maximum user flexiblity.

Apparently that was not helpful, not read or not understood.

Common rail would be a terrible idea on the little layout.

But don't take my word for it.

I fixed my problem.  Had a set of feeder wires crossed.  Now running with one turnback, two DPDT switches, and will add another turnback and a DPDT switch.

You got that right!
