context_page_description: The Chūō Main Line, commonly called the Chūō Line, is one of the major trunk railway lines in Japan. It connects Tokyo and Nagoya, although it is the slowest direct railway connection between the two cities; the coastal Tōkaidō Main Line is slightly faster, and the Tōkaidō Shinkansen which is currently the fastest rail link between the cities.
  The eastern portion, the Chūō East Line, is operated by the East Japan Railway Company, while the western portion, the Chūō West Line, is operated by the Central Japan Railway Company. The dividing point between the two companies is Shiojiri, where express trains from both operators continue to the Shinonoi Line towards the cities of Matsumoto and Nagano. Compared to the huge urban areas at either end of the Chūō Line, its central portion is very lightly traveled; the Shiojiri-Nakatsugawa corridor is only served by twice-hourly local and hourly limited express trains.
  The Chūō Main Line passes through the mountainous center of Honshu. Its highest point is about 900 meters above sea level and much of the line has a gradient of 25 per mil.
