HO Scale? What did I buy now?

looks like a good haul. you may well have a mix of couplers, as some suppliers have their own special kind that arent too compatible with others.
it looks to be HO scale, and the tyco controller essentially confirms that as i dont think they made any other scales.

i thinking the jupiter is missing a smoke stack. i have a bachmann one, with different colors. on this page, under "other locos" http://sunsthomasandfriends.weebly.com/h...rains.html

would love to see some clear photos of the rolling stock. looks like a santa fe crane, and a chattanooga caboose?
