Biggest in the World

It's Railroad Days in Pacific, and special guest Union Pacific Railroad locomotive Challenger No. 3985, the only operating engine of its class in the world, made a whistle stop this morning for about 2,000 train fans who took photos of this huge mechanical marvel built in 1943, retired in 1962, and restored in 1981. The engine alone weighs 627,900 pounds. It runs on No. 5 heating oil.
