Progress Rail has announced the signing of a new agreement with Norfolk Southern (NS) that will see the company modernise a set of 96 EMD SD70M-2 locomotives – transforming them into SD70ICC units equipped with AC traction technology.
The upgraded design transformation will enable three modernised SD70ICC to carry out the work of four legacy SD70M-2s, allowing NS to move the same tonnage with fewer locomotives, reduce overall fuel consumption and improve performance.

Each modernised SD70ICC unit will include a remanufactured EMD 16-cylinder 710 engine rated at 4,300 horsepower, as well as updated control systems and Caterpillar Advanced Diesel Engine Management (ADEM), all of which are hoped to reduce both unplanned downtime and yield significant fuel savings depending on duty cycle.
Norfolk Southern Vice President of Mechanical and Chief Mechanical Officer, Brian Barr, said:
These conversions are a tangible example of how we’re modernising our fleet to drive safe, reliable, and efficient operations for the long term.
By upgrading to AC traction, we’re strengthening network resilience, improving fuel efficiency, and extending the life of our assets — while giving our customers greater haulage capacity and the consistent service they need to support their own growth and sustainability goals.
Delivery of the new units will commence in 2027 and be completed by 2029.
