First off I would like to say that model is absolutely beautiful. Absolutely stunning and capturing ever small detail, even down to using the correct wheel set and the Grey Hound livery, which is rare to see, even in the world of model trains. Wondering what the gear drivetrain pieces are used to get the 3:5 ratio. And the hypothetical weigh it can pull at certain speeds. I will definitely be on the look out for when the instructions are released. As this would be a perfect candidate for a passenger consist. Cheers.
