EMD to Release New Tier 4 Freight Locomotive

October 28, 2015

Listening to our customers, understanding what they need, and providing a reliable, cost-effective solution? Sounds like a recipe for success, and that’s exactly the formula used by Electro-Motive Diesel (EMD), a wholly owned subsidiary of Progress Rail Services Corporation, a Caterpillar company, when building the new EMD SD70ACe-T4 freight locomotive. The SD70ACe-T4 is designed to meet stringent emissions standards without the use of urea after-treatment, resulting in substantial savings for the railroads. It’s the result of intense research and analysis utilizing the joint expertise of EMD and Caterpillar engineering teams – with the mission to achieve life-cycle-cost optimization for customers. 

The teams used a robust design review process, incorporating more than 250 pieces of customer feedback to create 82 design changes even before steel was cut. The result? The locomotive’s final prototype design includes world-class fuel efficiency and an isolated alternator and engine – reducing vibration while providing a quieter cab and requiring less maintenance for surrounding parts. A new alternator start system means improved reliability. The redesigned cab has been expanded, providing more headroom and increased visibility for improved ergonomics and safety. And it’s all powered by an EMD 12-cylinder 1010 engine, resulting in improved asset utilization, optimized efficiency and performance, and lower infrastructure and maintenance costs.

The team’s goal was to bring a product to market with the quality and maintainability our customers have come to expect. By listening to customer requirements for the new Tier 4 engine and incorporating those requirements into the design, the team created a locomotive with the safety, performance and life-cycle cost our customers want and need. Ahead of the schedule previously announced by Progress Rail, the new locomotives will be available for customer purchase in the second half of 2016.
