@Norton posted:Easier to go 3 rail to 2 rail than the other way around. Two rail wheelsets usually come one side insulated. Obviously all 3 rail wheelsets would have to be swapped.
Three rail loco and truck frames are usually narrower to accommodate the thicker wheels. At most you can shim the axles. Going two to three rail you likely have to mill the frames. Been there, doing that.
