Target class: CBTC signaling system Context triple: [Siemens Trainguard MT, instanceOf, CBTC signaling system]
-
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.
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.
-
C.
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.
-
D.
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.
-
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.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
