It is currently preserved in the climate controlled Frederick J. Lenfesty Center. |  |
| Minneapolis, St. Paul and Sault Ste. Marie Railroad (Soo Line) | H-23 class (4-6-2) | 2718 George Banta Jr. | Built by Alco in May of 1924, 2718 was the first piece to ever arrive at the museum. While technically obtained after the 261, it arrived earlier in the day than the 261. For the first few years of its time at the museum, the 2718 pulled excursion trains on the Soo Line's mainline with sister locomotive 2719. It was formerly retired in the early 60s. 2718 was donated by the Soo Line on March 10, 1958 and arrived at the museum later that year.

| Sumter & Choctaw Railway | 2-8-2 | 102 | Built in June of 1924 by Baldwin, 102 is the only steam locomotive that still traverses the museum's working loop. While it arrived at the museum with a cracked boiler and has never steamed there, in 1988 the Green Bay and Western Railroad's Norwood shops built a faux tender for it using parts for a GE 45 ton diesel switcher. It is normally used for special events as the tender is underpowered and prone to overheating. 102 was donated June 5th, 1962 by the Marathon Paper Division of the American Can Co. It is currently sitting in the Victor McCormick Train Pavillion and it's original tender sits outside, behind the building. |  |
| United States Army | 10-36E 2-8-0 | 101 | Built by Baldwin sometime between 1916 and 1918, the 101 is the last example of it's class in preservation. After serving the United States Army in country during the first and second world wars, the 101 was shipped to Korea in 1951 to fight in the Korean War. While in Korea, it became property of the Republic of Korea and during this time it's cab was blown up. It was discovered by Col. George Simpson (who later became museum director) and reconstructed by Army Transporation Troops. 101 was donated in 1958 by President Sygman Rhee of the Republic of Korea. It is currently preserved in the climate controlled Frederick J. Lenfesty Center. |  |
| Union Pacific Railroad | 4000 class "Big Boy" 4-8-8-4 | 4017 | Built by Alco in December of 1944, Big Boy 4017 is one of the 8 remaining Big Boy type locomotives. An impromptu attempt to bring the locomotive to steam in 1970 was reportedly attempted by visiting rail crew from the Flying Scotsman, but was aborted after 20 tons of coal failed to heat the boiler enough to produce steam. [11] 4017 is the only Big Boy with a tender (from Big Boy 4023) from the 1944 order of Big Boys, whose tenders held a larger fuel capacity. 4017 was donated in July of 1961 by Chairman of the Union Pacific Railroad, E. Rolland Harriman (for whom 4017 was once named). |  |
