Wow, that is simple, Steve.  Simplicity has its elegance.

I have downloaded a video clip that shows this in action.  I was very
impressed.  I liked the gearing available to select the rotation rate/throw.

This came up a couple of days ago, but I finally came up with a design
for a coupler that (1) is not connected to the trucks, (2) pivots to
allow the cars to negotiate the curves, (3) centers itself when the car
is being pushed, and (4) pivots to negotiate curves while the car is
being pushed backwards. The coupler could use some improvements, but the
basic design idea works.

I posted some pictures on my site

I like this one, too, because it looks like it could be hidden under a flat • bed
car.

Your coupler design was the design that started this thread. I was wondering if
there was a way to keep the coupler straight when going backwards. That is all.
Each solution has its advantages, and I like all three!

P.S. Your stairs, the black hinge pieces attached to the 2x2-2x2 90° brick, are
what inspired the stairs on my 8-wide SD40-2. Mine are a bit too big though.
