Caterpillar’s Progress Rail to Upgrade 96 Locomotives with 4,300 HP Engines
Caterpillar’s Progress Rail will upgrade 96 SD70M-2 locomotives to AC traction between 2027 and 2029 using remanufactured 16-cylinder EMD 710 engines producing 4,300 hp. Conversions boost reliability by 40%, increase haulage capacity by 55%, improve fuel efficiency by 3% and extend locomotive life by at least 20 years.
1. Contract Scope and Timeline
Progress Rail will upgrade 96 Electro-Motive Division-built SD70M-2 DC locomotives for Norfolk Southern, converting them to SD70ICC Tier 2+ AC units. Deliveries are slated from 2027 through 2029, with each conversion extending asset life by at least 20 years.
2. Technical Enhancements
Upgrades include individual axle control, Cat’s Advanced Diesel Engine Management and remanufactured 16-cylinder EMD 710 engines producing 4,300 horsepower to optimize traction and performance on heavy-haul routes.
3. Operational Benefits
The conversion program is designed to improve fleet reliability by 40%, lift haulage capacity by 55%, reduce fuel consumption by 3%, and allow Norfolk Southern to operate fewer locomotives per train.
4. Strategic Impact for Caterpillar
This agreement bolsters Caterpillar’s aftermarket services revenue and reinforces Progress Rail’s role in fleet modernization, positioning the company to capture additional rail sector upgrade and maintenance contracts.
