About us

Established in 1991, GRAW specialises in design and manufacturing of the geometry measurement systems for the railway and steel industries, including rails, turnouts, track and wheels.

GRAW produces microprocessor-based portable devices for geometry control of the railway, such as trolleys for tracks and turnouts that can be fitted with GPS or laser range finder, track and turnout gauges, rail and turnout profile gauges, as well as measuring instruments for the rolling stock wheels.

GRAW is a developer of the large measuring systems like real-time track condition evaluation systems for track geometry vehicles, stationary wheel geometry control systems, and diagnostic databases for rolling stock wheels maintenance planning.

The company also has experience in development of the software for collecting, processing, reporting, and archiving the measurement data. Moreover, GRAW has experience resulting from the requirements put forth by the railways, light rail, metro, and tram operators, track maintenance companies and companies regenerating worn tracks and rails.
