The engineer of UP FEF-2 821 puts the hammer down as he tries to get the first section of train 23, the
San Francisco Challenger out of Cheyenne on time. During WWII, trains like the Challenger often ran in two, three, or even sometimes as many as four sections as traffic levels reached new peaks. As passenger miles carried by US railroads climbed to 93 billion in 1944, railroads struggled to put together complete streamlined consists of prewar times: form was replaced by function as section sleepers and coach seats became more valuable than single rooms and private accommodations. The UP alone hauled 5,481 passenger miles in 1944, over a 7000% increase from a depression-era low of just 436 passenger miles in 1933. This kind of cobbled-together consist pictured here is typical of wartime priorities in the makeup of passenger trains.
