The Dash 8-40BW, or B40-8W as some call it, is a four-axle road diesel locomotive built by GE Transportation Systems for the Atchison, Topeka and Santa Fe Railway (ATSF) in the early 1990s. ATSF was the only railroad to order it, 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.

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)

All of ATSF's B40-8Ws are now part of BNSF Railway, and many of them have been repainted into BNSF's orange, yellow, and green "Heritage 2" paint scheme.
