B40-8W Diesel Locomotive

Prototype Information

The GE Dash 8-40BW, or B40-8W, is a four-axle diesel locomotive built by GE Transportation for the Atchison, Topeka and Santa Fe Railway (ATSF) in the late 1980s and the early 1990s. It is part of the GE Dash 8 Series of freight locomotives.

The locomotive model designation is interpreted as follows: B (B type truck arrangement, 2 axles per truck) 40 (4000 horsepower) –8 (the generation when it was designed, in this case meaning the late 1980s) W (Widecab).

ATSF was the only railroad to order the B40-8W, and a B unit (cabless booster unit) was almost made with it, but because the price would have been the same for B40-8Ws with cabs or without, they decided to order units with cabs only.

All of ATSF’s B40-8Ws were passed on to BNSF Railway, with some later sold to other railroads.
