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.

As I remember, the nomenclature is for a two part semi drop in decoder is TCS-CN
However...I do not believe it is still made today.
A few years ago, I came upon a distressed Altas SD-9 which was already equipped with such a decoder but came with one more decoder still in the package.
This became one of my favorite projects and ultimately one of my best runners.
I took it down to it's base parts, and then ran toothpaste through the geared trucks, running them back and forth on track, till I felt them loosening up, cleaning them with a water pic,
There was a high spot on the Worm Gear...Corrected.
But as I recall several other parts needed a bit of fine sanding and filing. Once all the parts were a bit freer, and fitted > I oiled the worm gear assembly only, and reassembled.
The previous owner believed the shell had been melted but it turned out to be only the D&RG Decals. The shell broke down into three parts and were easily painted with a light spray of Rustoleum Camouflage Paint...I renumbered it 5350 in large numerals.
This became a primary tester for long runs on my DCC Main Layout.
Good Runner ? YES!
However, I happened to have a similar SD in Brass sitting near by. Just for a Look See, I placed the Brass shell over the Atlas Chassis
It hunkered down, making even better contact with the track; without being overly weighted.
>>> Since that day, I have modified several Brass Shells to fit over more modern (5 pole) chassis locomotives both in N and HO Scale; while being converted to DCC.
As for your first question....
On Track Detection.
I am working on it....
Via three very different approaches.
This is one of them....
Just showed up on eBay one day with a. Buy it Now for $300 and I pushed the button.
I also own Digitrax and ESU ECoS....
Wish me Luck
