In order to have a bit of switching puzzle fun, I put a loop of MTH O-31 up with a couple of O-31 switches to create a 3-2-2 inglenook area. I have been using conventional controls and a screwdriver (to open couplers) but I would like to switch to DCS and electrocouplers for the locomotive.
What DCS switchers might be out there with electrocouplers and would look ok with smaller rolling stock? Particularly looking for older models that might be easier to find on the secondary market.
Thanks!
