The MRS scoured the US for usable narrow-gauge locomotives and rolling stock, and soon a strange and colourful assortment began arriving at Skagway. The single largest group was seven D&RGW K-28 class 2-8-2's acquired prior to the lease in August 1942. 2-8-0's from the Silverton Northern and the Colorado & Southern, all over 40 years old, and a pair of ET&WNC 4-6-0's soon appeared, among others, as well as eleven new War Department Class S118 2-8-2's. WP&Y's original roster of 10 locomotives and 83 cars was soon eclipsed by the Army's additional 26 engines and 258 cars.
