Where Are All 8 Big Boy Locomotives Now

25 Union Pacific Big Boys were built. 17 were scrapped. Only one still breathes. See where all 8 surviving Big Boy steam locomotives are today, and why 4014 got a second life when the other seven didn't. One derailed and killed its crew, then went back to work. One spent 51 years at a California fairground. And one isn't even wearing its own tender. Where all 8 Big Boys are now: 4006 – National Museum of Transportation, St. Louis, Missouri 4004 – Holliday Park, Cheyenne, Wyoming 4017 – National Railroad Museum, Green Bay, Wisconsin 4018 – Museum of the American Railroad, Frisco, Texas 4023 – Kenefick Park, Omaha, Nebraska 4005 – Forney Museum of Transportation, Denver, Colorado 4012 – Steamtown National Historic Site, Scranton, Pennsylvania 4014 – Union Pacific Steam Shop, Cheyenne, Wyoming (still running) Which frozen Big Boy would you bring back next?
