Railway line in Japan From Wikipedia, the free encyclopedia
The Iida Line (飯田線, Iida-sen) is a Japanese railway line connecting Toyohashi Station in Toyohashi, Aichi with Tatsuno Station in Tatsuno, Nagano, operated by Central Japan Railway Company (JR Central). The line links eastern Aichi Prefecture and southern Nagano Prefecture through northwestern Shizuoka Prefecture. It goes through steep mountains as well as cities such as Iida and Ina. The line was originally four different private railway lines, the first of which opened in 1897.

The line has an unusually high number of so-called Hikyō stations, or hikyo-eki, which have since lost their nearby communities due to depopulation.[1] There are 94 such stations along the route.[1] The line has been described as the "holy land for those who love touring hikyo-eki".[1] The phrase was coined in 1999 by Takanobu Ushiyama and friends, for railroad stations that are isolated and little used.[1]
Traveling the entire length of the 195.7 km (121.6 mi) line by local trains takes six hours.[1]
The limited express Inaji (伊那路) runs between Toyohashi and Iida twice a day. The rapid Misuzu (みすず) runs between Iida and Okaya. Local service is generally divided into three parts by Hon-Nagashino and Tenryūkyō stations. The section near Toyohashi functions as commuter rail for the city, while the section between Hon-Nagashino and Tenryūkyō is a mountain railway with fewer passengers.
All trains stop at stations marked "●" and pass stations marked "-", "↓", or "↑". Arrows indicate the direction of rapid trains. Some trains stop at stops marked "▲".

The Toyokawa Railway opened the section from Toyohashi to Toyokawa in 1897, extending the line to Omi in 1900. At the northern end, the Ina Electric Railway opened the Tatsuno to Ina-Matsushima section (electrified at 1,200 V DC) in 1909, extending the line to Tenryukyo in sections between 1911 and 1927. The Horaitera Railway opened the Omi to Mikawa-Kawai section in 1923, and electrified it at 1,500 V DC in 1925 in conjunction with the electrification of the Toyohashi to Omi section the same year. The Toyohashi to Toyokawa section was double-tracked the following year. The Sanshin Railway opened the Tenryukyo to Kadoshima section as an electrified (1,500 V DC) line in 1932, the Mikawa-Kawai to Toei section (and all subsequent stages) as an electrified line in 1933, and connected the two sections (completing the line) in 1936. All four companies were nationalised in 1943.
In 1955, the overhead line voltage of the Tatsuno to Tenryukyo section was increased to 1,500 V DC.
CTC signalling was commissioned on the line between 1983 and 1984, and freight services ceased in 1996.
