On a fine Saturday morning, Henry and Sumner head with their family to Steamtown National Park. They are so excited because there is nothing Henry and Sumner love more than locomotives and big steel machines
As their adventurous day leads them from a big Union Pacific locomotive to a real train ride and finally the museum, the children learn all about steam engines, the different locomotive cars, the duties of an engineer, and how a locomotive boiler creates steam.
In this educational children's tale, two siblings embark on a great adventure inside Steamtown National Park.
