Each set of six driving wheels is driven by two steam cylinders. In essence, the result is two engines under one boiler.
The Union Pacific Railroad sponsored development of this type to meet the need for higher speeds in main-line service. Historically, articulated locomotives had been limited to slow speeds by factors inherent in their design. The technical breakthroughs achieved with the Challenger enabled the carrier to develop the Big Boy with the same speed expectations.Speeds in excess of 60 M. While unheard-of on other railroads using articulated steam locomotives, became commonplace on the Union Pacific.
