Infrastructure Measurement Systems
Railway profile measurement and traffic-speed pavement evaluation from Greenwood Engineering — 30 years of infrastructure measurement expertise across rail networks and road authorities worldwide.
Wheel-rail contact profile
Domain 01 / Rail
MiniProf BT
Full-contact magnetic profiling · ±0.01 mm · All weather
MiniProf BT Wheel
Handheld tread and flange profiling for railway wheels. Evaluates flange height, thickness, qR, and Sd values for maintenance planning and safety compliance. Bluetooth to Criterion mobile app.
Flange wear & tread hollowing
Re-profiling decisions
Safety compliance checking
MiniProf BT Rail
Rail head cross-section profiling for wear assessment and grinding verification. Measures gauge corner, running surface, and head width against reference profiles stored in Envision software.
Wear assessment vs. target
Grinding quality verification
Gauge corner analysis
MiniProf BT Switch & Crossings
Profile measurement of switches, crossings, and special trackwork. Critical geometry verification for high-wear turnout components where deterioration directly impacts speed limits and safety.
High-wear turnout tracking
Frog and crossing geometry
Special trackwork profiling
Envision Software
Desktop analysis platform — trend analysis, wear evaluation, grinding assessment, profile library
MiniProf Criterion
Mobile app — Bluetooth field data collection, instant profile display, pass/fail reporting
Domain 02 / Pavement
Road & Runway Systems
Traffic speed — no lane closures · Network to project scale
Traffic Speed Deflectometer
Truck-mounted rolling wheel deflectometer measuring pavement bearing capacity at up to 80 km/h. Network-level surveys across thousands of kilometres without lane closures or traffic disruption.
Bearing capacity mapping
Per COST 336 standard
Roads & airport runways
Profiler
Advanced pavement profile measurement at traffic speed. Optional Surface Imaging System (SIS), right-of-way imaging, and GPR integration for comprehensive condition surveys with IRI, texture, and rutting data.
IRI, profile & texture
Optional GPR integration
Right-of-way imaging
LaserProf
Compact profiler mounted on a standard tow hitch. Single or dual laser configuration for quality control during paving, field supervision, and bike lane compliance measurement without specialist vehicles.
Tow hitch mounted
Paving QC & acceptance
Bike lane measurement
Deployment Scenarios
Where They Work
Wheel Maintenance
Routine wheel profile measurement for monitoring flange wear, tread hollowing, and re-profiling decisions. Extends wheel life, prevents derailment risk, and supports predictive maintenance scheduling. Criterion app delivers pass/fail on-site in seconds.
Rail Grinding Verification
Before-and-after profile measurement of rail heads to verify grinding quality, target profile compliance, and metal removal rates. Envision software compares measured profiles against design templates and generates compliance reports.
Switch & Crossing Monitoring
Profile wear tracking on high-traffic turnouts and crossings where geometry deterioration directly impacts safety and operational speed limits. Routine measurement intervals enable condition-based maintenance rather than time-based replacement.
Pavement Management
Network-level bearing capacity surveys with the TSD for prioritising road rehabilitation investment across hundreds or thousands of kilometres. Continuous deflection data at traffic speed eliminates the need for point-load testing and lane closures.
Airport Runways
Pavement strength assessment and surface condition surveys on runways, taxiways, and aprons without disrupting flight operations. Traffic-speed measurement during low-traffic windows delivers full runway coverage rapidly.
Road Construction QC
LaserProf quality control measurements during paving operations to verify surface profile compliance before acceptance. Compact tow-hitch mounting means any site vehicle can carry the system. Ideal for contractors managing paving acceptance and handover.
