The dividing point between the two companies is Shiojiri, where express trains from both operators continue north onto 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 lightly traveled; the Shiojiri-Nakatsugawa corridor is only served by one limited express and one local service per hour.Its highest point (near Fujimi) is about 900 meters (3,000 ft) above sea level and much of the line has a gradient of 25 per mil (2.5% or 1 in 40).The Chūō West Line parallels the old Nakasendō highway (famous for the preserved post towns of Tsumago-juku and Magome-juku) and the steep Kiso Valley.The Kaiji limited express terminates at Kōfu, the capital of Yamanashi Prefecture, while the Azusa continue beyond Shiojiri to Matsumoto via the Shinonoi Line.The Japanese Government Railways (JGR) then continued to extend the line, reaching Shiojiri the same year, and Tokyo (at Shōheibashi Station (昌平橋駅)) in 1908.[citation needed] Notes: On September 12, 1997, a Super Azusa limited express bound for Matsumoto collided with a 201 series local train that failed to stop at a red signal while passing through Ōtsuki Station.
