The locomotives are powered by a 16-cylinder diesel engine, and entered service in 2002. However, due to the harsh, hot and dusty environmental conditions, only a limited number of the original locomotives are still in use.

RAI wants to bring the complete fleet back into operation again through a repowering project which comprises the re-engineering of the locomotive, the supply, installation and commissioning of ABC 12DZC engines, and the installation of air intake filtration.
