During the twentieth century, the Union Pacific Railroadgained worldwide renown for the development and operation of high output locomotives powered by steam, gas-electric,and the internal combustion engine. What is less commonlyknown is that the railroad embraced the internal combustion engine shortly after the turn of the century—just 36 years after the driving of the Golden Spike—in the form of the gasoline-powered passenger motor car. Although overshadowed by later advancements, the passenger motor car, of which many design elements would later be adapted to the railroad’s famous Streamliners, were the inaugural application of internal combustion technology on the Union Pacific. The culmination of decades of research, this liberally-illustrated volume seeks to tell the definitive story of these unique entires to Union Pacific’s nationwide fleet.

UPHS Archives at the American Heritage Center of the University of Wyoming – The American Heritage Center is developing a digital library of the images and diagrams in the UPHS Collection at AHC. This is a long-term, gradual process; only a fraction of our images are digitized at this point. A long-run goal is to develop an indexed, searchable digital library of small scans of our images for the benefit of our membership and others.
