Sterling Colorado Trolley Motor Car Conductor 1910 Real Photo Postcard

The image depicts a Union Pacific motor car, specifically "Motor Car 10," at Sterling, Colorado, likely in the early 20th century. These self-propelled railcars, often gasoline-electric, were an innovative solution for railroads looking to provide more economical passenger and light express service on branch lines and routes with lighter traffic volume than required for traditional steam locomotives and full train consists.

Such motor cars, frequently equipped with sections for both passengers and U.S. Mail Express, were crucial for connecting smaller communities like Sterling to the broader rail network. Sterling, established in the late 19th century, thrived due to its agricultural output and position on the Union Pacific line, with these efficient railcars facilitating essential transportation, communication, and commerce in an era predating extensive road infrastructure.
