Twenty-five Big Boy locomotives were built for Union Pacific in the early 40's and were operated for nearly 20 years. UP acquired 4014 from a museum and rebuilt it in time for it to feature in the 150th Anniversary of the Golden Spike this summer. They're now taking it on a tour.
1.2 million pounds with 16 drive wheels, it sure was quiet!
4014 was running late. It had departed Yuma late, and as a result had been side-tracked several times while paying traffic moved through. It finally showed up nearly 2 hours late.
