QQ777 For example, the Chicago "L" Yellow Line (which uses tracks originally used by the North Shore Line) used overhead wires on the western half of the route, which transitioned into third rail for the eastern half of the route. For this Breitspurbahn railway system, electrification with a voltage of 100 kV taken from a third rail was considered, in order to avoid damage to overhead wires from oversize rail-mounted anti-aircraft guns.|Jepang: プレイステーション, Hepburn: Pureisutēshon?
