Rainbows in the Lehigh Valley Gorge

Todd, when I have done those split frame Bachmann's I like to isolate the frame too. I cut the clips that transmit the power from the track and soldier wires direct to the trucks and run them up through the center gap directly to the decoder. I isolate the decoder on a thin sheet of styrene. That way I don't have to be concerned about shorts to the frame.
