According to the website, they fit straight onto Atlas models, including the older Roco/Atlas models of the 70s. Not sure if any of you on the list are in need of these, but they are a big deal for me. I use Kadee trucks under all of my HO rolling stock and love them. Looking forward to purchasing in the next couple of weeks.
