How is the 2-6-6-2 articulated? Is it like the prototype with a solid and floating engine or is it like most other non brass locomotives both engines pivot?
I have a feeling both engine pivot. I have carefully examined the few available videos to see.
No matter, give me a few days to get the actual engine and I can tell you for myself, or one of the other forum posters who have it will.
I've seen the model at my LHS. The rear engine set is rigid, like the prototype.
