Progress Rail, Norfolk Southern announce order of four additional high-horsepower locomotives powered by new generation of Caterpillar engines

Albertville, Ala. & Norfolk, Va. - Sep 01, 2010


Progress Rail Services Corporation, a wholly-owned subsidiary of Caterpillar Inc., and Norfolk Southern have announced the order of additional EPA Tier 2 compliant, high-horsepower repower locomotives - designated the PR43C.

In 2008, Norfolk Southern and Progress Rail began a cooperative effort to develop the PR43C locomotive. Since then, two PR43C prototype locomotives have been built and placed in service on the Norfolk Southern system. These locomotives have been closely monitored during a series of developmental and operational testing. With the testing of the first two prototypes coming to a close, Progress Rail is pleased to announce Norfolk Southern has ordered four additional PR43C locomotives, scheduled for delivery later this year.


The PR43C locomotives are unique in the industry. Remanufactured from reusable locomotive cores, the PR43C locomotives have a dual-engine configuration. The primary engine, a Caterpillar C-175 rated at 3,600 horsepower, and a secondary engine, a Caterpillar C-18 rated at 700 horsepower, work in tandem to power the locomotive. By rebuilding the PR43C from a reusable locomotive core and providing 4,300 total horsepower, the PR43C locomotive serves as an environmentally-friendly solution for the rail industry.

"The PR43C's performance is optimized for the current duty cycle and operational needs of the railroads," said Ken Hofacker, senior vice-president of locomotive development for Progress Rail. "Our concept of large and small diesel engines working intelligently together maximizes fuel savings while minimizing emissions and lowering life-cycle costs."

"Progress Rail is extremely pleased to have had the opportunity to jointly develop this locomotive with Norfolk Southern," said Billy Ainsworth, president and CEO of Progress Rail. "Progress Rail and our parent company, Caterpillar Inc., share Norfolk Southern's passion for environmentally-friendly locomotives. This project is about maximizing fuel efficiency and reducing emissions, while taking a locomotive that was built 20-plus years ago and giving it another 20-plus years of life. Simply put, this is about building a sustainable locomotive."

"The PR43C meets Norfolk Southern's standards for high-quality locomotive performance, while at the same time satisfying our corporate sustainability objectives," said Tim Heilig, Norfolk Southern's chief mechanical officer. "Progress Rail deserves credit for building a fuel-efficient, low-emission locomotive that can handle heavy, long-haul freight demands."

The four new PR43C locomotives will feature upgraded traction systems, control systems, and modernized cabs.
