I converted these locomotives several years ago when I bought them new, so I don't have progress photos. What I do remember is that the instructions that come with the Digitrax DN145K decoder are accurate. This particular installation was the first successful DCC conversion I did (early 2000). The only improvement you should consider making is soldering the lips that make the electrical connection between the rail and the decoder. The instructions say to bend these around the decoder. However, I found that when you re-assemble the body shell, the lips may no longer make contact. The lips are soldered on the unit shown in the photo below (identified by the circles).
