New Haven Union Station is the main railroad passenger station in New Haven, Connecticut. It is the third such station in the city of New Haven, preceded by both an 1848 built station in a different location, and an 1879 built station near the current station's location. Designed by noted American architect Cass Gilbert, the present beaux-arts Union Station was completed and opened in 1920 after the previous Union Station was destroyed by fire. It served the New York, New Haven and Hartford Railroad for the next five decades, but fell into decline following World War II along with the United States railroad industry as a whole.

Springfield Union Station is a train and bus station in the Metro Center area of Springfield, Massachusetts. Constructed in 1926, Springfield Union Station is the fifth-busiest Amtrak station in the Commonwealth, and the busiest outside of Greater Boston.
