Reply to "MTH CSX SD40-2 with fixed pilot"

Peter,

   First, I use MTH Scaletrax which is a low profile T rail so the scale wheels have no problem running on them or through the switches.

 The 2nd thing is that this engine and many others I have are MTH Proto 3/2 engines which means they can run on both 3 rail and 2-rail track.   To run on 3 rail all you need to do is install the center rollers and flip a switch to 3-rail.   If I remove the rollers and flip the switch to 2-rail the wheels then take power from one side and ground from the other so I can run on 2-rail track.   The power can be either DC like you're used to or AC like I am running on my 3 rail layout.   There is another switch that allows you to switch between DCC or DCS control system.   You are limited to running on minimum 072 track because of the scale couplers and the wheels in some cases.

 To see another one of these proto 3/2 engines running on 2 rail track using AC power click here:   https://ogrforum.ogaugerr.com/...e-f7-s-modifications
