Locomotive, Steam, 2-10-0 Russian Ye

History: The Russian locomotive class Ye, and subclasses Yea, Yek, Yel, Yef, Yem, Yemv and Yes (Russian: Паровоз Е; Еа, Ек, Ел, Еф, Ем, Емв and Ес) were a series of 2-10-0 locomotives built by American builders for the Russian railways in World War I and again in World War II. They were lightweight engines with relatively low axle loadings.

Due to the Bolshevik revolution in 1917, 200 locomotives were stranded in the United States so these were fitted with wider tires: locomotive driving wheels had steel tires which were heated to expand them, then driven over the wheels so that they shrank into place. By fitting wider tires with a deeper tread width, the effective wheel gauge could be decreased from the Russian standard of 5 ft (1,524 mm) to 4 ft 8+1⁄2 in (1,435 mm) (the US standard) to fit the American gauge, and could then be sent to various railroads. The locomotives were nicknamed "Russian Decapods."
