Main Drive Plus Auxiliary Converter Components: REO-USA Reveals a One-Stop Shop at APTA EXPO

INDIANAPOLIS — Some railway component makers focus on Main Drives and others specialize in Auxiliary Converters. Few if any cover the gamut of both as fully as REO-USA. Attendees at the upcoming APTA EXPO can see for themselves when REO-USA (booth 4300) showcases an extensive range of railway components at the October 12-15 event, being held at the George R. Brown Convention Center in Houston.

"Integrated solutions can enhance both short- and long-term performance and payback for railway equipment and service providers," contends Barbara Miller, REO-USA Vice President of North American Operations. The company's 25,000 sq. ft. headquarters in Indianapolis is ISO 9001 certified; German-based parent company REO is IRIS certified.

"Our end-to-end railway applications expertise and firsthand know-how ensure that individual or interrelated products for the U.S. market can be tailored as needed to more cost-effectively meet user demands. Of course, our extensive raw material selection also simplifies procurement. We partner with companies in China and India as well as Europe, enabling us to quickly and efficiently respond to the needs of railway organizations worldwide while maintaining the highest quality standards."

Miller also indicated that every REO-USA railway component undergoes type testing in accordance with the EN 60310 standard, all part of the company's domestic testing capabilities. 

"Customers can submit components, such as a frequency converter, which can be integrated with our specially fitted testing stations for their modular units."
