New York, Susquehanna, & Western 2-10-0 "Decapod" Type Locomotives

Class J-2 (Locobase 66)

875 were ordered by the Imperial Russian government in 1916; many were delivered and that design was subsequently built in the many hundreds in the Soviet Union. Others went to Japan and 200 stayed in the US. Erie had 75, Seaboard Air Line took 40, Frisco 21, and the rest distributed to 22 other railroads including the New York, Susquehanna, and Western. Repeat orders came almost 30 years later from the Soviet Union.
