Continuous Cab Signal Systems

Continuous cab signal systems receive steady streams of signal aspect information from modulated carriers in the rails. 

This data is continually scrutinized by a safety-critical on-board computer that determines over-speed conditions and issues appropriate alerts and/or penalties.

PHW custom designs and builds these systems according to the specific territories and vehicles on which they will be used.

Examples of basic configurations include 4-Aspect, 9-Aspect, and Composite (multiple aspects, multiple territories) systems.

Typical system options include braking assurance, vehicle network interfacing, braking profile generation, and GPS.
