The locomotives replace the existing fleet of diesel locomotives and support the modernization of South Korea's freight transport. They will primarily be used on the central route between Seoul and Busan, which is one of the country's most important freight transport connections.

Long-Term Partnership

Korea Railroad (Korail) has previously used mtu Series 183 and 396 engines, including in the diesel-hydraulic vehicles of the Saemaul train, which was introduced between 1987 and 1993. Now, the Koreans are using the mtu Series 4000R for the first time.

On-Site Service

The South Korean distributor MEST takes over the technical support and service for the engines. MEST is responsible for mtu products and solutions and is a joint venture founded in 2016 by ENST Co. and Rolls-Royce Solutions Asia. Close collaboration with local partners is intended to ensure quick response times on site. This service quality was a key factor in the decision for mtu engines.
