Track geometry can degrade quickly, causing derailment risk. Measuring and monitoring track geometry is key to ensure safety and directing track maintenance efficiently.
Track Geometry Measurement System (TGMS)
The Track Geometry Measurement System (TGMS) is the fundamental system to directly measure all the key track geometry conditions such as gage (gauge), curvature, crosslevel, warp, twist, profile (surface, top), and alignment. Its measurements replace the manual measurements made by field personnel.
Vehicle/Track Interaction (V/TI) Monitor
Many track geometry conditions combine multiple factors to cause a derailment risk. The Vehicle/Track Interaction (V/TI) Monitor uses the actual rail vehicle response to the track to assess the track condition. The V/TI operates autonomously and is a great addition to the Track Geometry Measurement System (TGMS) to ensure complete track geometry condition assessment. Since the V/TI operates autonomously, it can find rapidly changing conditions.
Ride Quality Measurement System (RQMS)
The Ride Quality Measurement System (RQMS) has similar measurements to the V/TI Monitor, but with the difference that it can be synchronized with other measurement systems, such as a TGMS, and measure continuously allowing for strip chart data to be plotted alongside other measurement systems data.
