Researchers receive second patent for railroad track inspection system

HUNTINGTON, W.Va. – Two Marshall University professors have received a second patent for an invention they say will make inspection of railroad tracks safer, more accurate and less expensive than current methods.

Engineering professors Dr. Richard Begley and Dr. Tony Szwilski recently were notified that their Canadian patent application has been approved. It is the first Canadian patent awarded for an invention developed at Marshall. They were awarded a U.S. patent last year.

Their system, which uses a combination of GPS devices, cameras and ground penetrating radar to measure track wear and other problems, has taken more than 10 years to develop.
