Target class: railway signaling system component Context triple: [Westinghouse XCA248, instanceOf, railway signaling system component]
-
A.
railway signaling system
A railway signaling system is an integrated set of trackside and onboard equipment, rules, and communication protocols that control train movements to ensure safe separation, efficient routing, and protection against collisions.
-
B.
railway communication system
A railway communication system is an integrated network of technologies and protocols that enable real-time exchange of information between trains, trackside equipment, and control centers to ensure safe, efficient, and coordinated railway operations.
-
C.
railway infrastructure element
chosen
A railway infrastructure element is any physical component of a rail system—such as tracks, signals, switches, bridges, or platforms—that supports the safe and efficient operation of trains.
-
D.
railway coupling system
A railway coupling system is a mechanical assembly that connects railway vehicles together, transmitting forces for traction and braking while maintaining alignment and safe separation between cars.
-
E.
public railway
A public railway is a government- or publicly-owned rail transport system that provides scheduled passenger and/or freight services accessible to the general population, typically operating on standardized tracks and infrastructure.
- F. None of above.
