Target class: electric traction technology Context triple: [AC propulsion, instanceOf, electric traction technology]
-
A.
electrified railway
An electrified railway is a rail transport system in which trains receive power from external electrical sources, such as overhead lines or third rails, instead of relying on onboard fuel.
-
B.
electric transport system
chosen
An electric transport system is an integrated network of vehicles, infrastructure, and control technologies that enables the movement of people or goods using electricity as the primary energy source.
-
C.
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.
-
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.
public transport technology
Public transport technology encompasses the systems, vehicles, infrastructure, and digital tools used to plan, operate, and optimize shared transportation services such as buses, trains, trams, and metros.
- F. None of above.
