Good head of steam you have up in Bluto there, judging from the plume issuing forth from the safety valve.
Nice couple of engines ..... I'll look forward to spring when you can get videos of the 0-4-2 up for us to enjoy. At 7 1/2" gauge I rather suspect that one weighs in at a bit more that Bluto's 25 pounds!
And as for the last photo .... Oh WOW, I'll be right over to help you play with some of those wonderful trains!!!
