Operating cars. Mixing old with new

Why not just put a piece of O gauge operating track in place of the O27 operating track?  You'll most likely have to shorten a piece a regular O27 track somewhere next to it to make up for the difference in length.

Yes, my thought exactly. I have several modern operating cars that work fine on the O gauge UCS section. #6-65530.

if you can find the old o27 5 rail uncouple unload tracks you can put 2 together and wire them in parallel .then you have a track section about  16 inches long
