Optical Rail Measurement


ARM performs this critical step with highly accurate, state-of-the-art hardware and software.

• Measures actual versus desired rail profiles

• Measures gauge and cant angle

• Measures percent of vertical and gauge head loss

• Identifies rail type

• Performs trend analysis (wear versus tonnage)

• Forecasts short- and long-term maintenance and rail replacement needs

• Provides quality control through pre- and post-grinding measurements that determine metal-removal rates and verify that the desired profiles are in place.
