Standard Oil No. 1, a compact steam locomotive built in 1920, has returned to Casper after more than six decades at the Colorado Railroad Museum in Golden, Colorado. The engine spent 42 years switching tank cars at Casper’s Standard Oil refinery before retiring in 1962. Its return to Fort Caspar Museum restores a tangible connection to the city’s oil industry and railroad heritage.
The museum is raising $15,000 to support transportation costs, permanent placement, and cosmetic restoration. Plans include making the locomotive accessible for closer public exploration as restoration progresses. The project offers Casper an opportunity to preserve an important part of its industrial history and help future generations understand the industries and workers that shaped the community.
