Reply to "Is this possible? Use a Lionel Postwar (50/ 60’s) toggle controller with Vintage (80/ 90’) O27 track switch"

@SteamWolf, the 1121 does not have any provisions to provide positional feedback to a remote panel - it is all mechanical and so the 1121C or 1122C controllers with mechanical shutters can get out of sync as noted above:

The closest one could get would be the 1122C, but that only keeps track of the toggle commanded throws mechanically and not actually tied to the switch position and so it can get out of sync.
