How Just One Engine Destroyed the Steam Locomotive

In 1930, the chairman of Baldwin Locomotive Works stands before an audience of railroad executives and predicts that steam will dominate until at least 1980. His company has been building locomotives for nearly a century. The Eddystone plant outside Philadelphia stretches across 600 acres. At its peak, Baldwin employs 18,000 workers and builds over 2,600 locomotives in a single year. More than 70,000 machines roll out of its shops. They power every major railroad in America and half the railways on earth. Transcontinental freight, the entire industrial backbone of a nation — all of it runs on steam built in places like Eddystone, Schenectady, and Lima. But fast forward to 1956, and Baldwin is dead. Lima has been absorbed and demolished. ALCO is bleeding out. And diesel has taken everything. Total extinction. Now, there is a single machine in this story. It is the EMD FT demonstrator, unit number 103 — the locomotive that toured 20 railroads across 35 states and proved that one diesel set could replace nearly three steam engines. But the truth is more complicated — and more damning. Either way, what follows is one of the most complete technological extinctions in industrial history.
