China CNR Corporation Ltd. CKD8
In 2009, the Argentine state railway Trenes Argentinos ordered 20 CKD8 diesel-electric locomotives from the Chinese company CNR, together with 220 passenger coaches for long-distance traffic. Although they have six axles, they are only intended for use in front of passenger trains.
The engine used is the MTU 16V 4000 delivered from Germany, which has an output of 2,200 kW. 13 CKD8G and seven CKD7G were built for different lines. The CKD8G reaches 120 km/h, while the CKD8H is designed for 160 km/h and therefore has a lower tractive effort.
Another order came from Nigeria in 2014 and included the CKD8 for the upgraded route between Abuja and Kaduna. These locomotives have been in service since 2018 and have a top speed of 150 km/h.
