Kansas City Southern recently took delivery of the first two of 27 locomotives that will be repowered by Electro-Motive Diesel Inc. (EMD) this year.

The 710ECO™ Repower units will enable KCS to update 40-year-old yard and road switchers with the latest microprocessor-controlled locomotive engine technology to reduce emissions, increase fuel economy and reliability, and cut maintenance costs. The locomotives are designed to reduce greenhouse gas emissions by 70 percent, lower lube oil usage by 50 percent and cut fuel consumption by 25 percent compared with conventional switchers.

The 710ECO Repower units will feature eight-cylinder, 2,000-horsepower and 12-cylinder, 3,000-horsepower EMD diesel engine options for both low- and medium-horsepower applications, enabling KCS to tailor motive-power performance to specific requirements.

EMD is converting 27 SD40 and GP40 units to GP22ECO and SD22ECO repower units, and GP22ECO-M mother/slug combinations. Eleven of the locomotives will be used by Kansas City Southern Railway Co. (KCSR) and the other 16 units will be used by Kansas City Southern de México S.A. de C.V.

The repowered units will enable KCS to “meet our commitment to continuously improve railroad operations while simultaneously addressing future environmental concerns,” said KCSR Executive Vice President and Chief Operating Officer Scott Arvidson in a prepared statement.
