|Illinois Railway Museum|
The Illinois Railway Museum (IRM, reporting mark IRMX) is the largest railroad museum in the United States.   It is located at 7000 Olson Road  in Union, Illinois, 55 miles (89 km) northwest of Chicago.
Granted tax-exempt status in 1957, the museum aims to demonstrate the vital role railroads have played in the growth of the Chicago area and the United States as a whole. There are over 450 pieces of prototype equipment in its collection as well as numerous displays. Visitors may ride on some of the museum's electric, steam, and diesel-powered trains from April through October.
The museum was founded in 1953 by ten people who joined together to purchase Indiana Railroad interurban car 65.
Originally called the Illinois Electric Railway Museum, the museum was renamed in 1961 to reflect its expanding scope. Initially located on the grounds of the Chicago Hardware Foundry in North Chicago, Illinois, the museum's entire collection was moved in 1964 to Union along the former right-of-way of the Elgin & Belvidere interurban. Two years later, operations began using Illinois Terminal interurban car 415; in 1967, the first steam engine was operated. The first storage barn was erected in 1971. In 1981, a one-mile (1.6 km) streetcar loop was constructed. A 4.6-mile (7.4 km) railroad line was built during the 1980s and early 1990s.
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. Trolley bus operation occurs on the Saturdays of the Memorial Day, Independence Day & 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 trolley bus rides on a regular basis.
The Illinois Railway Museum property covers more than 80 acres (32 ha) of land  and has the most extensive physical plant of any rail museum in North America. In 2009, the museum purchased an additional 89 acres (36 ha) of adjacent land to secure a buffer against future development.  The main campus is located at .

The Illinois Railway Museum is an IRS Chapter 501(c)3 nonprofit corporation owned and managed by its membership. Museum management includes a board of directors, elected by the regular membership of about 160 active volunteers. A board president is elected by the directors. The board oversees the general manager, a volunteer who in turn has oversight over an array of department heads. Major departments include Steam, Diesel, Electric Car, Passenger Car, Freight Car, Track & Signal, Buildings & Grounds, Trolley Bus, Motor Bus, and Operations. Other departments oversee the museum's libraries, electrical infrastructure, and display and education functions. Most department heads are volunteers. All workers at the museum fall under the direct authority of one of the department heads. The vast majority of workers are volunteers. Anyone who is interested in trains or other collections/aspects of the museum is actively encouraged to volunteer, with required training done by the museum.
IRM has been used in several films, due to its proximity to Chicago and its extensive collection of historic railroad equipment. In the 1992 film A League of Their Own, starring Tom Hanks, Geena Davis and Madonna, the museum's depot was used for several small-town depot scenes; other scenes featured with the Nebraska Zephyr and only surviving EMD E5. The 1993 movie Groundhog Day featured the museum's EMD SD24 diesel locomotive. The museum's grounds and some of the passenger cars were used in the movie The Babe, starring John Goodman. In late 2005, the Burlington 9911A and several coaches operated to Chicago for filming in Flags of Our Fathers, a Clint Eastwood film. The initial sequence of 2008's The Express was shot at IRM. The most recent film Transformers: Age of Extinction starring Mark Wahlberg, released in 2014, made IRM the host of several scenes. 
Many television shows' railroad sequences have been shot at the IRM. Scenes depicting steam era operations in the late 1920s were shot for the 1993 television series The Untouchables. The hit show Chicago Fire features the IRM onsite in the season 2 episode "No Regrets."
The museum hosts a series of annual special events, of which the most popular is the Day out with Thomas event in July. Other recurring events include Bunny Trolley Hop around Easter, Chicago Day in June, which commemorates the end of streetcar service in Chicago in 1958; the annual July 4th Trolley Weekend; the Vintage Transportation Extravaganza including one of the largest antique car shows in the state on the first Sunday in August; Diesel Days in mid-August; Museum Showcase Weekend in mid-September; "Bus Day" the last Saturday of September; and "Happy Holiday Railway" (weekends between Thanksgiving and Christmas).
