So this is more of a "putting the feelers out" kind of question but, as usual, there is some back-story. Basically I have the same problem a lot of folks do, limited space. On top of that I also enjoy automation, continuous motion, and layouts with grades. Because of the limited space and the fact that, because I'm military, I move often, I tend towards smaller, more mobile layouts that can be torn down. The problem I've been experiencing has been that there do not seem to be a lot of steam engines w/ Odyssey or Odyssey II that can also handle the O-36 turns I use. I have been using a semi-vision Big Boy for the time being, however, as I look to expand the collection, I'm finding fewer and fewer appealing options. Most of what I've been able to find requires at least O54.
So can smaller engines which can negotiate O-36 and smaller turns be "easily" modded for speed control or do I just need to sit and wait patiently for more engines to be released that have this tech packed in to it? Is it too much to ask for a Berkshire that can handle O31?
