Baldwin Locomotive Works: Evolution of the American Locomotive, 1907

Innovation Required

As Baldwin set out to build the first U.S. steam locomotive, the range of complexities they would encounter could not have been foreseen. Building a machine for the conversion of fuel energy, mostly coal, to mechanical transport energy required innovation at every single step of the way. In the beginning, the materials available were elemental metals, such as iron and copper, and wood. The tools necessary for high precision engine parts were scarce and unsuitable for mass manufacturing. So even the tools to make the parts—to make the locomotives—had to be invented first.
