Great Western 90 is a preserved 12-42-F class 2-10-0 "Decapod" steam locomotive owned and operated by the Strasburg Rail Road (SRC) east of Strasburg, Pennsylvania. Built in June 1924 by the Baldwin Locomotive Works, No. 90 originally pulled sugar beet trains for the Great Western Railway of Colorado, and it was the largest of the company’s roster. In April 1967, No. 90 was purchased by the Strasburg Rail Road.
