Question: how do tgv trains work?
Answer: Basically, a TGV is an electric high-speed train designed for speeds of 199 mph (320.259 km/h) (TGV Duplex). It works by picking up electric current through a device called a pantograph which touches an overhead power line called a catenary. ... Fun fact: a heavily-modified TGV once reached 354 mph (570 km/h).
