RRAddict:
If you operate MTH DCS or Lionel TMCC/Legacy, you really don't need a special track. I converted my Lionel milk car with the ERR ACC Mini Commander several years ago. So now I can activate it anywhere on my layout with the MTH or Lionel remotes.
What is great about that, I can have several platforms located at different spots on my layout and don't have to be concerned about buying a special track to activate the car. I can release milk cans anywhere I want with either remotes.
You should check it out. It's simple to install and works great. Go the Sunset 3rd Rail and look under ERR.
