Kenya Railways and UK-based power and propulsion systems group Rolls-Royce have announced that three of the former’s heavy haulage locomotives have been re-engined with the latter’s mtu Series 4000 engines. The locomotives were 40 years old and had actually been retired from service, so the refit has rejuvenated them and brought them back into service. All mtu engines are produced by Germany-based Rolls-Royce Power Systems. The operation was undertaken by Rolls-Royce Solutions Africa, which has a branch in Kenya but is headquartered in South Africa. The project was carried out in collaboration with Malaysia-based rail engineering services group SMH Rail.
