A tribute to the "Big Boy" locomotives produced by Union Pacific, "Last of the Giants" shows the end of a memorable era in Western Railroading, you'll see the development of steam power on the Union Pacific from 4-6-0s, 2-8-0s, and 2-8-2s up to 2-10-2s and even 4-12-2s, shown through film, photos and animated diagrams. This is followed by the development of compound articulated Mallets and simple articulateds such as the Challengers.
Measuring 132 feet long and weighing one and one-quarter million pounds, the Big Boys were appropriately named. These were the largest and heaviest of their type and could pull a loaded 5-1/2 mile long train on level track. Their tenders carried a massive 28 tons of coal and 25,000 gallons of water; and with a heavy train a Big Boy could use all of this up in the first half of a 57-mile rum. Although there were only 25 Big Boys ever built, they ran up a total of nearly 26 million miles in 18 years, hauling billions of tons. - Kohs & Company
