Great Western 90 is a class 12-42-F 2-10-0 "Decapod" steam locomotive owned and operated by the Strasburg Rail Road (SRC) east of Strasburg, Pennsylvania. Built by the Baldwin Locomotive Works in June 1924, 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, and has been pulling excursion trains there, ever since.
