AOAView

Wayside angle of attack & B2B measurement


Trimble® AOAView is a wayside angle-of-attack (AOA) measurement system that is designed to measure AOA on both wheels of a wheelset simultaneously.

In-track angle of attack and back-to-back measurement

Extremely accurate measurements

Since AOAView is installed on a tie (sleeper) between the rails, it provides a reliable angle of attack measurement as track fluctuations due to dynamic loads do not affect where the measurements are performed. Also, AOAView provides extremely accurate measurements of back-to-back distance of wheel sets with multiple measurements from both wheels of an axle.

Provides multiple measurements

AOAView is also capable of measuring tracking position and axle back-to-back dimension. The system is installed between the rails and has sufficient clearance with respect to the rail for most rail grinding machines and other track maintenance equipment to pass through the location without interference.

Dramatic time and cost savings, versus manual inspections

Complete AOA measurement quicker, minimizing time taken, costs, and issues that disrupt service.

Rolling stock stays in service for longer

With accurate measurements at mainline operational speeds there is minimal disruption to rolling stock schedules.

Limits risk to personnel, works 24/7, even in tough environments

AOAView works in even the toughest environments and at night so field workers are not in unpleasant or unsafe working conditions thereby reducing the risk to their safety.

Digital accurate records, with automated reporting

Providing digital records that are usable across operations and maintenance PantoView reduces manual and paper-based workflows saving time and money. Remote monitoring data can be reported on automatically so that corrective actions can be taken with less impact on service.
