The history of the labor movement in the Western United States is one dominated by the unions representing the major industries such as mining and railroading. The papers in Caine collections 22-24 chronicle railroad union activity on the Oregon Shortline (later the Union Pacific) of Idaho, Utah, and Oregon. Specifically the collections contain records from the Brotherhood of Locomotive Firemen, which later became the Brotherhood of Locomotive Firemen and Enginemen; the Women's auxiliary to the Brotherhood of Locomotive Firemen and Enginemen; and the Brotherhood of Railroad Trainmen. These records were found together in the Oddfellows Hall in Montpelier, Idaho, at which location the unions held their regular meetings. The records span the period from 1884 through 1954.

Construction of the Oregon Shortline Railroad, a subsidiary of the Union Pacific Railroad, began in 1881 and was finished in 1884. The line left the mainline of the U.P. at Granger, Wyoming and joined the Oregon Railway and Navigation Company line at Huntington, Oregon. By the end of 1882, the company had built 330 miles of track. The route of the road came through Montpelier, so that in 1883 this Idaho farming community became a division point for the railroad. By the turn of the century a shop and roundhouse had been built in the Idaho town. Town histories indicate that the Brotherhood of Locomotive Engineers established a lodge in 1883. Another union, the Brotherhood of Locomotive of Firemen's Re-Echo Lodge 195 moved their headquarters from Shoshone, Idaho to Montpelier in 1887. The earliest records in this collection chronicle the B.L.F.'s Re-Echo Lodge 195 and date back to 1884 when the lodge was headquartered in Shoshone, Idaho.

he railroad was a boon to Montpelier and became the main employer of that town into the 1950's. However, as trains became faster and more powerful and as engines changed from steam power to diesel, the need for a large railroad work force in Montpelier declined. By the 1950's many of the union men were moved to the divisional headquarters in Pocatello.

These railroad labor records cover important periods for the American labor movement. They document union activity through two world wars as well as the Great Depression. They also describe a period in which railroad employment played a key role in small western towns such a Montpelier, Idaho. In addition, the papers recount the difficulties of a manufacturing type of industry blending into a religious farming community.
