caption_attribution_description: English: Hanshin Railway Mukogawa Station in the mid- 1950's. Left side track is dual gauge. 日本語: 阪神電気鉄道武庫川駅。この写真は鉄道関係の出版物などでよく武庫川線開業時のものとして掲載されているが、出典と思われる阪神電鉄社史「輸送奉仕の50年」(昭和30年3月25日発行)にはそのような説明はない(汽車と電車が仲よく走る三線式軌道 -昭和18.11開通 同線武庫川駅付近― 同書)。むしろ停車中の1121号の尾灯(兼標識灯)が二灯化されておりドア部にも本線の大型化に対応するためのステップが設けられていること(いずれも1950年代前半に実施)、行先板の表示が「武庫川･洲先」となっていること、さらに1957年には1121号に代わって国道線の71形が運行されていることから撮影は1954年と思われる。左側の三線軌条を通過するのは蒸気機関車牽引の国鉄の貨物列車。
context_page_description: The Tōkaidō Main Line is a major Japanese railway line of the Japan Railways Group network, connecting Tokyo and Kōbe stations. It is 515.4 km long, not counting its many freight feeder lines around the major cities. The high-speed Tōkaidō Shinkansen largely parallels the line.
  The term "Tōkaidō Main Line" is largely a holdover from pre-Shinkansen days; now various portions of the line have different names which are officially used by JR East, JR Central, and JR West. Today, there are no passenger trains that operate over the entire length of the line, so longer intercity trips require several transfers along the way.
  The Tokaido Main Line is owned and operated by three JR companies:
  East Japan Railway Company
  Central Japan Railway Company
  West Japan Railway Company
