The Union Pacific 4-8-8-4 Articulated Mallet is the most beautiful and useful locomotive the world has ever seen.

This locomotive was given to the National Railroad Museum by E. R. Harriman, Chairman, and A. F. Stoddard, President, of the Union Pacific Railroad. On July 8, 1961, Vice-President E. H. Bailey, presented this locomotive to the National Railroad Museum at the formal opening of the Museum.

The 4017 was accepted for the Museum by H. E. Fuller, Chairman.

This locomotive is one of the 25 built in 1941 and 1942, termed Big Boys.

They are the largest steam locomotive ever built.

The Big Boys represent the supreme achievement of the age of steam. This locomotive operated from 1942 to 1949, over a million miles between Cheyenne and Laramie, Wy. and Ogden, Utah.
