Track Grinding Quality

Railgrinder - Wikipedia

The grinding quality index (GQI) is a software-based template used to measure the profileof a rail. This allows the desired rail profile to be compared to the actual rail profile. GQI software makes use of laser-based hardware mounted to the front and rear of the rail grinder. The use of laser-based hardware on maintenance of way vehicles such as rail grinders allows workers and contractors to take precise measurements of the rail profile before and after grinding. The GQI is rated from 0 (low priority) to 100 (
