Norfolk Southern said its new Automated Track Geometry Measurement System (ATGMS) will transform locomotives into inspection platforms on wheels by continuously scanning and evaluating track conditions.
The digital inspections will operate autonomously and under load while trains are in motion, the company said, essentially turning the locomotives into moving inspection platforms. Unlike traditional inspection methods that rely on dedicated geometry cars and manual checks. Officials said the ATGMS approach will increase the frequency of inspections without disrupting operations or requiring additional equipment.
“We’re now positioned to accelerate innovation and validate autonomous tech solutions with AI that directly support industry-wide safety and performance goals,” Mabby Amouie, AVP Enterprise Data & Analytics, said.
The ATGMS system is powered by advanced sensors and lasers mounted under locomotives and will measure things like alignment, gauge, elevation and curvature. The data captured will detect changes that could indicate potential defects like broken rails, deteriorating ties or shifts on the track. The system will go beyond early defect detection, the company said, and will enhance predictive maintenance, improve employee safety, boost operational efficiency and support compliance with Federal Railroad Administration (FRA) safety standards.
The company said it is already operating the ATGMS locomotives on several key corridors.
“ATMGS will offer operations the ability to test more dynamically, more frequently, and with greater precision,” Dustin Lange, senior director of engineering, said. “Combined with territory specific knowledge and experience, ATGMS helps track inspectors decide where their time and skills are needed most.”
