GE B39-8
The 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.
