The C&LS model is strictly 2-rail. As we've established here on the forum, there is no easy way to convert a 2-rail loco to 3-rail (it's difficult but possible to go the other way).
I did not know we established that. I posted a conversion a couple years ago. A forumite sent me a Lobaugh Berkshire, two rail, and a Williams Mike, three rail, and I converted it for the privilege of keeping the Lobaugh mechanism. I might be persuaded to do the same for the far more exotic Bultmann - marry it to the T1 mechanism. I get to keep all the leftover parts.
Be a shame to cut up Henry's fine work, but that is at least an "easy way."
