We went to Boone, IA on Monday and watched 4014 come in.
 |
| Got this off internet - taken Tuesday west of Boone. Under full power! |
 |
| Me in front of 4014 |
 |
| 4014 as it was arriving Boone, IA 4-15-19 |
 |
| A diesel was pulled along as insurance in case trouble with steam engine so it could pull train to siding. |
 |
| Baggage car closest, followed by a power unit, I imagine to make electricity for the passenger train. |
 |
| There were a lot of people on the train, coming from Omaha Tickets for the ride range in price from $400 to $750, and will benefit the museum. |
Pretty good size crowd out to watch the train. Quite a few local police as well as Union Pacific Police continually getting the people back to a distance. The passengers all got off and there were at least 3 charter buses there to take them back to Omaha. A diesel unit took the passenger cars back to Omaha.
Twenty-five Big Boys were built exclusively for Union Pacific Railroad, the first of which was delivered in 1941. The locomotives were 132 feet long and weighed 1.2 million pounds. Because of their great length, the frames of the Big Boys were "hinged," or articulated, to allow them to negotiate curves. They had a 4-8-8-4 wheel arrangement, which meant they had four wheels on the leading set of "pilot" wheels which guided the engine, eight drivers, another set of eight drivers, and four wheels following which supported the rear of the locomotive. The massive engines normally operated between Ogden, Utah, and Cheyenne, Wyo.
There are seven Big Boys on public display in various cities around the country. They can be found in St. Louis, Missouri; Dallas, Texas; Omaha, Nebraska; Denver, Colorado; Scranton, Pennsylvania; Green Bay, Wisconsin; and Cheyenne, Wyoming.
Big Boy No. 4014 was delivered to Union Pacific in December 1941. The locomotive was retired in December 1961, having traveled 1,031,205 miles in its 20 years in service. Union Pacific reacquired No. 4014 from the RailGiants Museum in Pomona, California, in 2013, and relocated it back to Cheyenne to begin a multi-year restoration process.
