Bridgelall Presents RAILS Research to Student AREMA Chapter

Posted: May 23, 2019

UGPTI researcher Raj Bridgelall was an invited presenter at the March meeting of the NDSU Student Chapter of the American Railway Engineering and Maintenance-of-Way Association. Bridgelall presented on his Railway Autonomous Inspection Localization System (RAILS) research effort to about 18 transportation and logistics and civil engineering students. RAILS uses low-cost sensors mounted on railroad equipment to collect information on unusual track conditions and their locations. This "big data" approach uses location data (already collected and transmitted by locomotives) and information from sensor accelerometers and gyroscopes to detect and identify the location of track anomalies. Railroads can use RAILS to plan and schedule more focused inspections at the highest risk locations to determine remediation needs. The system targets rail and roadbed-related accidents, the largest cause of rail accidents behind human error and failures in signaling and equipment.
