Herbert is a crazed, jingoistic patriot from America's heartland. Tough and having a high horspower engine, he is versatile, capable of switching and pulling, and is a great starter for newly-hired engineers.
Though he wanted desperately to work for Union Pacific, Herbert was rejected by the railroad. Undaunted, he was forced to work for the ASTF. He decided to make a career in running on ASTF trains on UP's rails via trackage rights, Herbert's crew placed a icebox and cabinets in him before embarking on a long train on the Mojave Subdivision for which he was awarded several medals that his engineer designed and made himself. He was sold to the Dock Railway and now works there in a paint scheme of BCDR black and gold.
Herbert is based on a EMD GP35.
