Constructing slab track calls for fast, precise measurements and immediate feedback. Trimble GEDO in combination with the software Trimble GEDO Track is a simple, integrated system to measure for precise adjustments, inspections and quality checks. In one operation, the Trimble GEDO captures the 3D coordinates of the track, together with gauge and cant. The information is compared to the design, and offsets and correction values are displayed in the field, where work crews make the necessary adjustments. With its precision measurement systems, Trimble GEDO is suitable for conventional and high-speed rail construction.
Time saving
Reduce time for documentation and acceptance. Capture adjustment and track acceptance data and quickly prepare reports for contractors and quality inspection.
Easy reporting
Satisfy reporting requirements with graphical and list form output of corrections for side and height correction plates.
Total confidence
Verify slab and track geometry with accuracy and confidence. Precise optical positioning and a simple, self-contained trolley provide flexibility and reliable results.
Design validation
Import alignment design from digital or paper plans. Check design information before it goes to the job site.
A system optimised for slab track construction, adjustment and verification.
• Precision Sensors: Gauge measurement range: –20 mm to +60 mm with ±0.30 mm accuracy / Cant (superelevation) range: ±9° (optionally ±10°) with ±0.5 mm accuracy
- Modular Hardware: Uses the lightweight, aluminium GEDO CE 2.0 trolley, adaptable to multiple gauges via extensions and also supports the GEDO Track Bar for slab-track or constrained environments
- Multi Sensor Positioning: Supports GNSS, optical total stations, and inertial sensors
- High Productivity: Up to 1.2 km/h using total stations / Up to 3 km/h with GNSS configuration
- Design Comparison On Site: Field software in Trimble Access Rail (GEDO Track) compares measured gauge, cant, and 3D track position against alignment designs in real time
- Slab Track Deployment: Special configurations (elevated trolley and Track Bar) support slab track installation, measuring horizontal/vertical position, gauge, cant, and rail inclination—outputting correction values and acceptance reports for quality control
