The Illinois Railway Museum (IRM, reporting mark IRMX) is the largest railroad museum in the United States.[1][2] It is located in the Chicago metropolitan area at 7000 Olson Road in Union, Illinois, 55 miles (89 km) northwest of downtown Chicago. History The museum was founded in 1953 by ten people who joined to purchase Indiana Railroad interurban car 65. Originally called the Illinois Electric Railway Museum, the museum was located on the grounds of the Chicago Hardware Foundry in North Chicago. In 1961, it was renamed to the Illinois Railway Museum to reflect its expanding scope. In 1964, the museum moved to Union, Illinois along the former right-of-way of the Elgin and Belvidere Electric Company. In 1968 the first steam locomotive was operated at the museum. The first storage barn was erected in 1972. In 1981, a one-mile (1.6 km) streetcar loop was constructed.[3][4] The right-of-way the museum was constructed next to still had back taxes into the 1980s. To gain full use of the track, the museum paid the back taxes, and gained the 4.6 miles (7.4 km) of railroad track to add to their property portfolio.[5] In 2016, the IRM purchased a 130-foot turntable from Union Pacific's former Denver & Rio Grande Western Burnham Shops complex in Denver for $10,000. The turntable is large enough for any locomotive in their collection, and will be used to store their steam locomotives, along with a planned roundhouse.[6] There are over 500 pieces of equipment, and over 100 acres of land owned by the museum.[4] Operations The museum's operations are primarily concentrated around its main campus just east of Union. Train rides are offered on the main line as well as the streetcar loop. Electric trains are operated from April through October and diesel and steam trains from the beginning of May through the end of September. Trolleybus operation occurs on the Saturdays of the Memorial Day, Independence Day, and Labor Day weekends, as well as on "Bus Day"; the last Saturday in September or the first Saturday in October. IRM is one of only two railway museums in the country that operates both electric and diesel trains, and the only one to offer trolleybus rides on a regular basis.
