The steam locomotives were truly awesome. I remember seeing one of the “Big Boy” locomotives in a museum when I was a kid. Truly amazing piece of machinery.

I agree. BTW the “Big Boy” is back on the tracks somewhere.

The linkage system that moves the slide valves have always fascinated me. Those old guys knew how to make use of the enthalpy behavior of steam for maximum power. They also knew the mechanical kinematics needed to adjust the flow of those valves with the timing necessary to maximize energy usage. I find the material difficult to follow.

Then, as if the former wasn't enough, the steam-powered water injectors work the same problem to a different purpose.

Those designers and builders were brilliant!

My Dad would bring us to Bellows Falls Vt. every year to visit Steam Town and see the Engines and memorabilia of that era. I loved to see and get close to them. Unfortunately the collection was sold told to someone in Pennsylvania I believe back in the 80’s. I think they had one of the largest Steamers every built on display in Vt.
