The Illinois Railway Museum has restored perhaps the oldest bicentennial diesel locomotive in existence. Ingersoll-Rand 91 was the eighth production diesel locomotive ever built and was constructed in 1926 by a consortium of American Locomotive Company, General Electric and Ingersoll-Rand. The 300-horsepower diesel engine was perfect for low-speed switching and was sold to the Delaware, Lackawanna & Western as its 3001. As the only locomotive at IRM to have been given a special patriotic livery for the bicentennial, I-R 91 was selected by Diesel Department volunteers for cosmetic restoration during the nation’s semiquincentennial year. The museum intends to eventually restore the locomotive to operation, which would make it the oldest operational diesel-electric locomotive in the country.
