Inspect critical turnout components and assess tie condition automatically — all at up to 120 km/h.
Simultaneous 2D imaging and 3D scanning replace multiple legacy systems in a single pass.
1 mm × 1 mm × 0.1 mm scans deliver unmatched clarity of rails, ties, fasteners, and ballast.
AI-powered analysis ensures consistent, objective results across repeat runs.
Validated in the field and trusted by rail operators globally.
The Pavemetrics® Laser Rail Inspection System (LRAIL™) is a next-generation 3D vision system that transforms railway inspection. In a single pass at speeds up to 120 km/h, LRAIL captures both high-resolution 2D images and 3D profiles of rails, ties, and ballast — delivering unmatched clarity and repeatability.
Powered by advanced Artificial Intelligence, LRAIL automatically detects, measures, and grades all critical components, including ties, clips, joints, switches, crossings, and rail surface wear. The result is a comprehensive, objective inspection that enables railways to prioritize maintenance, extend asset life, and reduce costs — without disrupting operations.
Built on Pavemetrics’ proven LCMS® technology, deployed in over 45 countries worldwide, LRAIL delivers field-validated accuracy that rail operators and regulators trust for safer, more efficient networks.
Operates at up to 120 km/h with full automation and no disruptions.
Compatible with narrow, standard, and wide gauges.
Simultaneous 2D high-resolution imaging and 3D point cloud generation in a single pass.
Automated change detection and grading of ties, fasteners, joints, switches, and crossings.
Operates day and night, immune to lighting/shadow conditions, with compact 13 kg sensors in rugged, sealed enclosures.
Anchor inspection, ballast level & fouling, elastic fasteners, rail geometry, rail head profile & wear, road crossings, turnout components, tie condition, tie plates & spikes.

LRAIL Comparison to Track Geometry Measuring Trolley (TGMTs) and Manually Operated Devices (MODs)
Owing to the design of TGMTs and MODs, the EN 13848-1:2003+A1:2008 requirements have to be modified. Therefore, this annex lists in tabular form the minimum requirements for each track geometry parameter which can be measured by TGMTs and MODs. Requirements differing from EN 13848-1:2003+A1:2008 are highlighted in bold. The requirements of EN 13848-1:2003+A1:2008 are shown only for comparison purposes.
