Mid-20th Century
The Kelso Depot served as a significant element in the Union Pacific’s contributions to the American war effort during World War II. The end of World War II marked the beginning of a long decline in the depot’s utility. The sharp decline in the volume of freight traffic and diesel engines replacing steam caused a reduction in services and the need for fewer employees. The Vulcan Mine closed early in 1947, further reducing freight and passenger traffic. A surge of activity occurred with the outbreak of the Korean War in the early 1950s, resulting in a renewal of high traffic levels on the Union Pacific line for several years.
In 1953 and 1957, attempts were made to market the low-grade iron ore stockpiled at the Vulcan Mine. However, higher horse power, second generation diesel-electric locomotives of the 1960s resulted in the further decline in Union Pacific personnel needed at Kelso. This technological change eliminated the need for helper locomotives entirely in 1959. Coupled with the closing of the station agency and cessation of passenger train service to Kelso on August 14, 1964, this development spelled the end of the depot’s principal function with the exception of the Lunch Room which remained serving until 1985.
