Just months before Pearl Harbor, the American Locomotive Company delivered the first Big Boy to the Union Pacific Railroad. The UP's Department of Research and Mechanical Standards had designed the locomotive for a specific task: to pull a 3600-ton train unassisted over the Wasatch Mountains in Utah. While the Big Boy is often cited as the biggest steam locomotive ever built, in fact it is not. The Norfolk & Western's Y6 and A, the Duluth Missabe & Iron Range's Yellowstones, and the Chesapeake and Ohio's Alleghenys were all in the same league, and some exceeded the Big Boy's weight and power.

In 1964 and 1965, New York City hosted the last of the great international expositions to be called a World's Fair. Built on the site of the 1939-40 World's Fair at Flushing Meadows, Queens, the 1964/1965 New York World's Fair was served by the IRT #7 Flushing Line of the city's subway system.
