TB 70 METRO LIGHT RAIL LINES Flashcards
TB 70 METRO LIGHT RAIL LINES
Light Rail Vehicles (LVR) consists of track and stations that are fed electrically by a Catenary System as opposed to a third rail system like the Red/Purple line.
The 34.5 kV AC is converted by a transformer/rectifier to 750-volt DC and fed through the Pantograph via Catenary lines in order to operate passenger vehicles.
