Union Pacific FEF Series - FEF-2

FEF-2

The second batch of fifteen was delivered in 1939. These had several improvements, including larger cylinders, better tractive effort, taller driving wheels, and smoke deflectors on the sides of the smokebox. The greatest change, however, was the provision of a fourteen wheeled “pedestal” or “centipede” tender, in place of the twelve wheeled ones of the first twenty locomotives. Thus, the first locomotives became known as "FEF-1," whilst these were known as "FEF-2."
