Integrated System Control Unit

The central hub of ISC's onboard architecture, the Integrated System Control Unit links passenger information, communication, and security subsystems into a single, coordinated platform. It manages data flow between the train and wayside infrastructure, enabling real-time updates, centralized diagnostics, and simplified maintenance across the fleet.
Passenger Emergency Intercom

A ruggedized, fail-safe intercom that gives passengers a direct line to the operator or control center in an emergency. Built for the vibration, temperature extremes, and heavy daily use of rail transit, it's designed for instant activation and clear two-way audio when it matters most.
Communication Control Head

The operator-facing interface for managing onboard announcements, intercom calls, and system alerts from the cab. It consolidates multiple communication functions into one ergonomic control point, reducing operator workload and response time during normal operations and incidents.
Passenger Information Signs

High-visibility electronic displays that deliver real-time, route-specific information — stops, destinations, connections, and service alerts — directly to passengers inside the vehicle. Content updates dynamically and integrates with the broader ISC information system for consistent, accurate messaging fleet-wide.
