UP #4014 Big Boy Headed To Cheyenne!
Only Union Pacific’s 4014 Big Boy can bring out legions of railfans!
Union Pacific’s 4014 Big Boy is ceremoniously being pulled by Union Pacific’s SD70 numbered 4014!
The open coal tender is staffed with Union Pacific employees waving to the railfans on the bridge overhead as Big Boy leaves the Colton, California, yard on her 1000 mile journey to the Union Pacific Steam renovation facility in Cheyenne, Wyoming.
In 2013, Union Pacific Railroad began the project of restoring 4-8-8-4 Big Boy No. 4014 to her original working condition!
In late April, 2014, this 4-8-8-4 Big Boy No. 4014 began her 11 day trek to Cheyenne, Wyoming including a total of 27 scheduled photo stops for her railfans!
Union Pacific built 25 of these Big Boy monsters back in 1941 through 1944!
Although operators sometimes called her Fat Girl, the Class 4000 4-8-8-4 was originally called Big Boy due to a worker that chalked the name on her fire box during construction!
Known for their size, power and reliability, the Class 4000 4-8-8-4 was the largest and most powerful steam locomotives ever built.
