Even in retirement, Old Number 4004 remains an imposing sight.  The world's largest steam locomotive, this powerful coal-fired engine was designed to pull a 3600-ton train over steep grades between Cheyenne, WY and Ogden, Utah.  The 4004 is one of the eight remaining Big Boys on display throughout the country.

On display year-round in Holliday Park. The engine is in the southeast corner of the park. You can park your car in the lot accessible from East 17th Street and Morrie Avenue.
