For more than 100 years, Progress Rail has produced the most durable, reliable and sustainable locomotive products and services in the rail industry. Progress Rail designs, manufactures and sells the iconic EMD^® locomotives for all commercial railroad applications. Over 65,000 EMD-powered locomotives delivered to more than 75 countries. Our technology leadership and superior performance drive our reputation for exceptional quality, service and innovation.

Many of the core technologies powering the GT46AC locomotive for 1520 gauge were first introduced with the SD70ACe platform in 2005. This powerful and efficient locomotive integrates the reliable 16-cylinder 710 engine, our EM2000™ microprocessor control system and AC traction.

The GT46AC is driven by advanced technologies, providing safety, reliability, efficiency and sustainability, while delivering optimized life-cycle cost. This service-proven workhorse demonstrates leading performance even while operating in harsh conditions.

Thousands of EMD-powered freight locomotives operate in heavy-haul service across the globe, including North America, South America, the Middle East, Africa and Australia. Built on this expertise and utilizing extensive engineering design, testing and validation, the GT46AC locomotive meets the latest Eurasia Economic Union Technical Regulation requirements and can perform successfully in demanding operating environments.
