Hi Guys, nice to see all this interest. My experience with O gauge is mostly 2 rail. I have converted newer Lionel 3 rail to RailPro with can motors. I do not go with open frame or any AC motors. You guys can quickly educate me on what you need for 3 rail.
The continuous current rating is 6 amps. The lighting outputs are rated at 1.2 amps . When you go above , like a smoke unit the RailPro displays an error. I do not suggest to any 3 railers this will replace Lionel or MTH control systems with all the same features.
In the 2 rail models all is good. With Lionel 3 rail and MTH we would remove their electronics and replace with the RailPro board. Why would you do that? Because you want on-board radio control with great sound, battery power, independent operations and no track cleaning.
