Wayside E-Type Coupler Securement Inspection System

Trimble® CouplerView®-CrossKey is an automatic wayside detection system that is designed to inspect E-Type coupler securement components at mainline speeds. It uses a high-speed strobe digital imaging system to acquire multiple images of every cross key (draft key) and the surrounding area for inspection.

The system inspects the cross key and its securement mechanism. Failure of such securement parts is a source of delay and derailments in freight operations. It operates on passing trains at mainline operational speeds up to 85 mph (140 km/h). All cross keys are imaged from both front and back—including the area under the center sill for proper E/F coupler classification.

  • Classify E-type and F-type couplers
  • Detect missing cross (draft) key
  • Find missing retainer-pin (t-pin)
  • Detect missing cotter key
  • Find missing cross key retainer washer

Dramatic time and cost savings, versus manual inspections

Automate and complete E-Type coupler securement (cross key/draft key) component inspections 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

CouplerView 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 alerts of issues

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

Easy to install system minimizes disruption and cost

CouplerView requires no track structure modification for ease of installation.
