Plymouth Diesel Locomotive #2038

This Plymouth 20-ton switcher was purchased by the Army Corps of Engineers in April 1941 to develop and supply Camp Roberts, near San Miguel in San Luis Obispo County. Operated by the Quarter Master Corps as #Q.M.C. 2038, the locomotive switched railroad cars of munitions and supplies for over 430,000 soldiers who were trained at the camp during World War II. It was the only locomotive operated at Camp Roberts. After being declared surplus and sold, the little diesel spent time at a construction company, a quarry, and a caboose-themed lodging facility in the Sacramento Valley. On September 21, 2018, Dwight Peterson Trucking delivered this acquisition to our display track. After some careful aligning and winching, #2038 touched its new home rails.

Ownership: Transferred from the Army Quartermaster Corps for sale by the War Assets Administration as of March 1947. Purchased by A. Teichert & Sons, Sacramento, CA on December 2, 1948. Purchased by El Dorado Lime and Mineral Co., Shingle Springs, California, on June 4, 1952. Possibly owned by Jim Dobbas, Inc., Newcastle, California, unknown dates. Purchased by Boyd Olney Jr. circa 1998. Inherited by Boyd’s son, David Olney, circa 2016.

Here’s a digital version of the Museum’s book Danny the Diesel Locomotive (#2038), by Glen Matteson, intended for ages about three to six. It’s free to view and download, but a donation of $10 will help continue Museum programs for our younger visitors. Click here to donate.
