| Union Pacific 4014 crests Summit on Cajon Pass as it nears its new home in Ponoma. Its January of 1962, and 4 Big Boys have already been scrapped, including sister unit 4015. 51 years later, 4014 will cross Cajon again, pulled by SD70Ms 4014 and 4884. 4014 is the only Big Boy in operable condition, as it was rebuilt by UP in 2016, becoming the first Big Boy to run on oil since 4005 70 years earlier.
