Just after Labor Day, Union Pacific Big Boy 4014 made the journey into Denver. For just over a month the Union Pacific Heritage Steam Engine did a trip on the eastern rails of the Union Pacific network. From Cheyenne east and eventually New Orleans, Denver was one of the final stops on the 2021 tour. I found a spot along a slight curve to watch the giant steam engine quick make a pass by the location as it headed to the Denver Union Station area.
There were twenty-five Big Boy engine made for Union Pacific. At 132 feet long they are the largest engines and are hinged in the middle to help them make curves. Big Boy 4014 was retired and in 2013 Union Pacific reacquired the engine from a museum for restoration which took six years to complete.
