RDS Railway Deformation System
The RDS (Railway Deformation System) is a system designed and developed for the automatic monitoring of railways. RDS consists of a
Digital MEMS tiltmeter mounted parallel or transverse to the track. Micro-prisms can be installed on RDS-T gauges to integrate the system with optical monitoring. RDS components are used to monitor settlement, heave, and twist of the track. The system is designed to be used on active tracks to ensure railway safety.
