China Railways HXD2B


HXD2B locomotives are railway locomotives 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 rather than the 'mouth' shaped form used in the HXD2.
An order worth €1.2billion for 500 units was made in 2006. The first 100 units were to be built primarily by Alstom, this number was reduced in 2007 to 10 units. The first Chinese-built unit was produced in December 2009. The order is expected to be complete by 2012.
