The Union Pacific railroad was constantly in search of more powerful locomotives to pull it’s long and heavy freight trains through the heavily graded mountain passes of the Rockies. One answer to that search was the articulated locomotive known as “Big Boy”. With a wheel arrangement of 4-8-8-4, “Big Boy” was one of the largest and most powerful steam locomotives ever built.
A cleanup is under way in the southern Minnesota town of Blue Earth, where 17 cars derailed on a train carrying corn, and 10 tipped on their sides. Mark Davis, Union Pacific spokesman says the 73-car train was carrying corn from Fairmont, Minn., to Blair, Neb., when it happened. The cause is under investigation, and theres no estimate yet on how much grain spilled.
