The Takasaki Line (Japanese: 高崎線, romanized: Takasaki-sen) is a Japanese railway line which connects Ōmiya Station in Saitama, Saitama Prefecture and Takasaki Station in Takasaki, Gunma Prefecture. It is owned and operated by the East Japan Railway Company (JR East).
All services on the line (excluding through Shonan-Shinjuku Line trains) run to/from Ueno Station in Tokyo via the Tōhoku Main Line. The line was extended to Tokyo Station via the Ueno-Tokyo Line that opened in March 2015.
The Ueno–Tokyo Line (Japanese: 上野東京ライン, romanized: Ueno–Tōkyō Rain), formerly known as the Tōhoku Through Line (Japanese: 東北縦貫線, romanized: Tōhoku-Jūkan-sen) is a railway line in Tokyo, Japan, operated by the East Japan Railway Company (JR East), linking Ueno Station and Tokyo Station, extending the services of the Utsunomiya Line, the Takasaki Line, and the Jōban Line southward and onto the Tōkaidō Main Line and vice versa. While on official maps the line is purple, rolling stock and signage show the line as orange stacked on green, the colours used by the lines it connects. The project began in May 2008 and was opened with the 14 March 2015 timetable revision, costing about JPY 40 billion.
Direct travel was expected to ease congestion on the Yamanote Line and Keihin–Tōhoku Line, and the travel time was reduced by around 7 to 10 minutes because of through trains between the lines of Utsunomiya and Takasaki and the Main Line of Tokaido in addition to through trains that pass the Shinagawa Station on the Joban Line.
Ueno Station (上野駅, Ueno-eki) is a major railway station in Tokyo's Taitō ward. It is the station used to reach the Ueno district and Ueno Park—which contains Tokyo National Museum, The National Museum of Western Art, Ueno Zoo, Tokyo University of the Arts and other famous cultural facilities. A major commuter hub, it is also the traditional terminus for long-distance trains from northern Japan, although with the extension of the Shinkansen lines to Tokyo Station this role has diminished in recent years. A similar extension of conventional lines extended Takasaki Line, Utsunomiya Line and Jōban Line services to Tokyo Station via the Ueno-Tokyo Line in March 2015, using existing little-used tracks and a new viaduct; the Ueno-Tokyo Line connects these lines with the Tōkaidō Main Line, allowing through services to Shinagawa, Yokohama, Odawara and Atami stations.
Ueno Station is close to Keisei Ueno Station, the Tokyo terminus of the Keisei Main Line to Narita Airport Station.
