The 1975–1976 American Freedom Train consisted of 26 cars during the U.S. Bicentennial, a predecessor to America250.
The traveling exhibition carried historic objects and cultural artifacts across the 48 contiguous states. Three steam locomotives hauled it in different regions, while diesel locomotives were also used on some sections because of track conditions and operating requirements.
The train began its tour in Wilmington, Delaware, on April 1, 1975, and completed its final visitor run on December 31, 1976. It stopped in 138 cities and attracted more than seven million visitors during its journey.
The Freedom Train is distinct from the earlier 1947–1949 Freedom Train. The later train was created specifically for the United States Bicentennial and included exhibition cars filled with American historical material.
