Norfolk Southern ATGMS: Real-Time Track Monitoring for Rail Infrastructure

“`html

Introduction

Norfolk Southern Railway has implemented a new automated track geometry measurement system (ATGMS) to enhance track condition monitoring.

System Overview

The ATGMS utilizes Norfolk Southern Railway locomotives to continuously assess track conditions in real time. This system contrasts with traditional inspection methods that use dedicated geometry cars or manual checks. The ATGMS operates autonomously while trains are in motion, thus increasing inspection frequency without requiring additional equipment or disrupting operations.

Technology and Operation

The ATGMS incorporates advanced sensors and lasers installed beneath locomotives. These components measure key track geometry parameters, including alignment, gauge, elevation, and curvature. The system’s data collection is designed to identify changes that may indicate potential defects, such as broken rails, deteriorating ties, or track shifts.

Conclusion

Norfolk Southern Railway’s ATGMS is designed to provide continuous, real-time track condition assessments using existing locomotive assets.

Company Summary

Norfolk Southern Railway: Operates a major freight railroad network in the eastern United States.

Technology

Automated track geometry measurement system (ATGMS): A system that uses sensors and lasers on locomotives to continuously scan and evaluate track conditions in real time.
