Halfway between Canela and Gramado, this gloriously eccentric museum is devoted to the history of steam power. A few hundred working models depict trains, ships, factories, mills, and stationary engines. A real Watt-style beam engine has been reassembled inside. The whole place hums and clanks with whistles, pistons, and condensing steam.
It is best known internationally for the sculpture on the facade: a full-scale steam train apparently crashing out through the front wall, a permanent recreation of a famous 19th-century railway accident. Even visitors uninterested in industrial machinery come for that one photograph. Open daily; great with kids.
