Strasburg Rail Road no.90 (ex: Great Western) is a 2-10-0 steam locomotive operated by the Strasburg Rail Road, outside Strasburg, Pennsylvania. It originally pulled sugar beet trains of about 40 to 50 cars length for the Great Western Railway of Colorado to the company's towering mill in Loveland, Colorado.
Built in 1924 by the Baldwin Locomotive Works in Philadelphia, Pennsylvania, #90 is the railroad's youngest engine; it is also the most powerful of the four steam locomotives in operation at the Strasburg Rail Road. The Strasburg Rail Road purchased it in 1968, and it is now one of the two last operating decapods in the United States.
