The Machine That Ended the Brakeman — The Westinghouse Air Brake

You are on top of a boxcar. The train is moving, and the engine has just whistled twice. That is the entire message: no radio, and nobody up here to say it again. It means the driver wants this train slower and cannot do it himself. Nothing on this train can stop it except you, and the two or three men strung out behind you along the other roofs. So you start walking — along a plank barely wider than your boots, over the gaps between cars, in whatever the weather is doing — with a hickory club to lever each brake wheel down, one car at a time. This is the story of the American railroad brakeman, and of the two machines that ended him. It is a job with a tool in a museum — the club at Steamtown is hickory, thirty-two inches long — and a safety system made of rope: tell-tales, hung across the track a hundred feet before every low bridge, on three-inch centres, so a man watching his wheel felt them hit his face and dropped flat. On the ground it was worse. Coupling cars meant standing between them and guiding an iron link into a socket by hand, and there was no such thing as the link-and-pin coupler: in the year to June 1891 the Interstate Commerce Commission counted forty-seven styles in use, and a man went into the gap not knowing which was waiting. In 1892, 10,697 of the 30,821 reported injuries on American railroads happened while coupling cars. The strangest part is who asked for the fix: in December 1889 President Benjamin Harrison told Congress that nearly ten thousand brakemen had petitioned the government to force the railroads to fit automatic brakes and couplers. Both machines already existed — Westinghouse's air brake, patented in 1869 and turned inside out in 1872 so a train breaking in two would stop itself, and Eli Janney's knuckle coupler of 1873, built like two cupped hands interlocking as the fingers curl, in the Supreme Court's words. Almost nobody had installed them. The Safety Appliance Act of 1893 made them law, and by 1902 coupling injuries had fallen to 2,256. The brakeman did not vanish; he worked another seventy years. What ended was the roof — and the last word on it is a federal regulation still in force, which orders the running board removed and six words painted on the side sill, an inch and a half high, in black on yellow.
