Yes, I looked at an online issue (March/April 2017) of the "O Scale Resource" earlier today; in it was an article about the guy who built some of the Max Gray engines...good stuff! I also remember a magazine that once had a great, long article about the Central Locomotive Works guy..."Bob...Smith(?)"

I feel ya. It's an "okay" treatment, but as I say, lacks depth. That's where guys like you, Carey, Jim, Ed, Dave (and others who helped me with my AN 4-6-0) could pool your vast collective knowledge and put together something pretty...swell.

PS: BYW: the "AN 4-6-0"; I was able to try it out this morning on a test loop (only 63" diam curves), but it actually runs pretty well. I do think that is too tight a curvature, but for now, it works. Thanks again to all of you who helped me.
