So what is the Semiquincentennial? Officially, in 2026 marks the 250th Anniversary for the United States of America. The Bicentennial in 1976, marked 200 years, railroads began painting locomotives to commemorate the significant year. These flashy red, white and blue locomotives are fondly remembered by enthusiasts and modelers. Coming into 2026, InterMountain adapts the scheme that was adorned on many 2nd generation diesel s into the present day. Each ET44AC Tier 4 GEVO has a significant year and is uniquely named representing the U.S.A.
