“BC Rail has 1441 main track miles running north-south in British
Columbia. Much of the northern branchline grades are geotechnically
sensitive. They are subject to freeze / thaw subsidence due to poor
ground / surface water drainage and local collapse from inadequate
bearing capacity for 100 ton car loadings. Our Roadmasters have found
the SolidTrack devices to be an accurate and effective means of
monitoring seasonal changes in the track geometry and ensuring that
safety standards are met.”

Technical Details
SolidTrack measures the following track parameters:
- Cross elevation
- Track Grade and changes in Track Grade
- Mileage and Speed (absolute track mileage & GPS)
- Track Warp in Tangents & Curves (62 ft chord). (Priority &
Urgent Detection)
- Track Warp in Spirals (31 ft chord). (Priority & Urgent
Detection)
- Track Twist in Tangents, Spirals & Curves. (Priority & Urgent
Detection)
- Beginning / End of Entry & Exit Spirals
- Excessive rate-of-change of Cross-Level in entry & exit spirals
- Curve Detection, length and radius of curve
- Under/Over elevated curves and spirals (Priority & Urgent
Detection)
- Negative cross elevation in curves. (Priority & Urgent
Detection)
- Given curve radius & cross elevation -> equivalent speed for
that curve.
- Harmonic Roll Detection (39 ft to 64 ft wavelengths). (Priority
& Urgent Detection)
- Gauge (Contact & Non-Contact - laser) - Wide, Narrow and gauge
variance detection (Priority & Urgent Detection)
- Alignment - 62' & 31' chord length. (Priority & Urgent
Detection).
