Class of Chinese diesel-electric locomotives
The HXN3 () (EMD classification JT56ACe) is a 6000 horsepower (4.5 MW) diesel-electric locomotive designed by Electro-Motive Diesel in the United States for export to China. All JT56ACe locomotives use AC traction motor technology and use the EMD H-Engine as their prime mover. The locomotives are capable of meeting the EPA's Tier 2 emissions regulations.
In September 2005, the People's Republic of China announced an order for 300 JT56ACe locomotives. The locomotives were jointly manufactured by EMD and China's own Dalian Locomotive Works. They are dual cab locomotives.
