Union Pacific Big Boy locomotives rarely, if ever, pulled passenger trains (according to one source they sometimes pulled troop trains), but as one of the largest steam locomotives ever built they proved fascinating to many passengers. Many large steam locomotives, such as the Great Northern 2-8-8-2s (which were rated as more powerful, as measured by tractive effort, than Big Boys), were designed to haul heavy freights at slow speeds of around 20 mph. But the Big Boys were built to go as fast as 80 mph and ordinarily ran at around 40 to 45 mph.

Aware of the public’s interest in the Big Boys, Union Pacific put one on display at the 1949 Chicago Rail Fair. This postcard’s claim that one Big Boy did the work of two other locomotives is true if the other two are 4-8-4 Northerns, as the Big Boy’s 135,000 pounds of tractive effort is more than twice the 63,000 pounds of tractive effort of UP’s Northerns. However, the Big Boy was only about 40 percent more powerful than a Union Pacific 4-6-6-4 Challenger.
