David Johnston posted:Something I have run across before is that the prewar locos connected center rail power between the engine and the tender. In post war locos the loco to tender jumper wire is outside rail power.
On my 1656 switcher I solved that problem by purchasing a three terminal female jack, p/n 201-4
and making connections to the center rail, outside rail and coupler all through a 3 wire tether. Worked like a charm.
