上野駅と浅草駅は1927年に開業しました。鉄筋コンクリートの技術がまだ未熟だったため、2本の線路の間の柱は鉄製でした。一部の改装は行われましたが、重厚な構造は以前と変わりません。
Ueno and Asakusa station were opened in 1927. Since the reinforced concrete technology was immature, poles between two trackes were made of steel. Although some refurbishment were taken into place, burly structure are the same as before.
