Description

The L class 2-10-0 was the first Russian locomotive to use Boxpok-type wheels, which were commonplace in steam locomotive design post-World War II. A casing between the dome and chimney covered a steam drier pipe.

History

It was designed and built by the Kolomna Locomotive Works shortly after World War II under supervision by L.C. Lebedyanski. It was originally designated Class P (for Pobyeda, "victory"), but was redesignated Class L in honor of its designer.

In conjunction with the FD class 2-10-2, it was primarily used to haul mainline goods across the terrain of the Soviet Union. Over 4,000 L class locomotives were constructed from 1945-1955, and they operated with the Soviet Railways until 1975.
