GE B39-8

A GE B39-8 is a 4-axle diesel-electric locomotive built by GE Transportation Systems. It is part of the GE Dash 8 Series of freight locomotives. Following the production of the first three units for the Atchison, Topeka and Santa Fe Railway, GE made many mechanical and electrical improvements that were reflected in a redesigned carbody for the remainder of production; these later units are sometimes unofficially referred to as B39-8E.
