I seem to remember an article in 009 News some years ago on adapting Kato chassis to DCC. Does anyone have a copy they could e-mail to me. Since I'm starting to model in 009 seems a good plan to go DCC.
I wrote the article which appeared in the August 2012 OO9 News and also Narrow Lines 198.
The diagram and instructions are also published on page 1010 of Railway Modeller December 2014 as a postscript to my Dean Hill articles. This will set you on the right track (sorry!) and after that the lighting wire setup is standard for any DCC decoder.
I have found that Digitrax DZ125 decoders work well as they are small enough for many OO9 locos.
Hope that helps.
Thanks very much Jim. I live in Brittany but will pick up a copy of December 2014 Railway Modeller when I return early next month! Thanks again!
