A track geometry car uses advanced technology to evaluate track safety in real time by using a variety of high-tech lasers, sensors, and cameras. Some of the things it measures: • Gauge (distance between rails) • Crosslevel (difference in height between rails) • Alignment (side-to-side straightness) • Surface (vertical smoothness) • Curvature If anything is out of tolerance, the system logs the location down to the foot, pretty cool! #railroad #railway #train #drone #rail #reels #reelsvideo #fbl
