Target class: train control system level Context triple: [CTCS-3, instanceOf, train control system level]
-
A.
train control system
chosen
A train control system is a coordinated set of hardware and software components that monitor, regulate, and automate train movements to ensure safe, efficient, and reliable railway operations.
-
B.
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.
-
C.
third rail electrification system
A third rail electrification system is a method of providing electric power to trains via an additional rail mounted alongside or between the running rails, from which current is collected by contact shoes on the train.
-
D.
electrified railway operation
Electrified railway operation is the management and control of train services powered by electrical energy supplied through overhead lines or third rails, encompassing infrastructure, rolling stock, power systems, and operational procedures to ensure safe, efficient, and reliable transport.
-
E.
rail transit
Rail transit is a public transportation system that moves passengers or freight along fixed steel tracks using trains, subways, trams, or light rail vehicles, typically in urban or intercity corridors.
- F. None of above.
