First, I have Kato Unitrack on my N scale practice layout. I want to accomplish detection and ultimately transponding. Based on Allan's turnout section and the Kato specific reco's I want to make the power routed turnouts not power routed. I believe the arm below with the red squiggle is the arm I am to clip. Confirmation would be really great so as to not ruin an expensive part of my layout.
Second, I recently purchased an Atlas SD-9, model #53508. My research shows that this was a 2003 build and that there was to be a DCC decoder for it the next year. Is there a decoder for this locomotive to make it DCC and if so what are my options? I would prefer a drop in version but I am not sure that is possible from what I can surmise from looking at the insides.
