China Railways HXD2B

The HXD2B is a 6 axle Co′Co′ locomotive designed for heavy freight mainline work.

The design is a single body twin cab locomotive with 6 axles in Co′Co′ wheel arrangement.

The body frame, traction motor power electronics and driver facilities are of a similar design as the HXD2.

The bogie design differs from the HXD2 using a straight welded steel frame[1] rather than the 'mouth' shaped form used in the HXD2.
