ATGMS at United States

ENSCO's ATGMS (Autonomous Track Geometry Measurement System) is an unattended track-inspection system mounted on revenue (in-service) trains. It continuously measures track geometry — gage, crosslevel, alignment, surface/profile, and limiting speeds in curves — and uploads data for analysis, enabling far more frequent inspection than manned inspection cars. Deployed on railroads in the US, Brazil, Australia, and Taiwan.
