-
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.
electric transport system
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.
-
E.
elevated railway
