The world's largest operating steam locomotive made stops in Muskogee and Claremore on Oct. 14. Union Pacific's Big Boy #4014 is on an eight-week, 10-state tour celebrating railroads and the communities they serve. 2 News Photojournalist Andrew Mohler was there when the iconic engine pulled into Muskogee. Union Pacific says Big Boy #4014 returned to service in 2019 after a 58-year retirement and a three-year restoration project. If there's any doubt "Big Boy" lives up to its name, it's worth noting the steam locomotive weighs in at more than 1 million pounds.
