Overview of the Bombardier SD40-2B

Explore the powerful SD40-2B diesel locomotive, a robust and reliable workhorse of the rails.

This locomotive, built by EMD and GMD between 1972 and 1989, is part of the renowned Dash 2 family and is derived from the SD40-2 series.

It saw service in the United States, notably operating with Burlington Northern as the BN SD40-2B class.

Boasting a top speed of 110 km/h, a weight of 170 tonnes, and a power output of 2240 kW from its EMD 16-645E3 prime mover, the SD40-2B was a true freight hauling stalwart.

Its dimensions, including a length of 20.98 meters, width of 3.13 meters, and height of 4.75 meters, coupled with its Co'Co' axle configuration, make it an iconic example of mainline diesel locomotives.

Refurbished by BNR, Bombardier, and Reggiane in 1980, it continued to deliver exceptional performance.

The SD40-2B represents a significant piece of railway history, embodying strength and engineering excellence in the world of rail transport.
