Holland also operates a Transit Testing hi-rail vehicle (TTV) that is designed specifically to accommodate the unique conditions on transit systems, including broad gauge, tight clearances, and tight-radius curves (up to 70 degrees). TrackSTAR 491 also incorporates a mini load axle to identify areas with poor tie/ fastener conditions.
Gauge face angle is becoming an increasingly important measurement in the railway industry, particularly on rail transit systems. Learn more in our recent white paper: Gauge Face Angle.
