a major Japanese public transport artery.
Runs from Otsuki to Yotsuya, in and near the Tokyo area (maybe further - I cant tell from my map), in the surface train capacity.

Most famous for its "peak hour" (read: sardines in a can) congestion, its inappropriately groping salarymen, and its popularity as the train to end it all in front of.
The later, perhaps, because of the frequent express services running along the line.

a colleague of mine once stated that his train (on the Chuo line) was delayed every day for over a week due "unforeseen circumstances" (read: salarymen ending it all).


The Chûôsen, or "Central Line," is one of the main intercity rail routes in Japan. It starts at Tokyo Station and ascends through the western suburbs of Tokyo, going up into the Japan Alps and then descending again to terminate in Nagoya, a total distance of 413 km (about 260 miles).

Most of the Chuo line was laid down around the turn of the century: the entire line was completed in 1904, although portions of it in the major cities date back as far as the 1870's. When the line first opened, under the private ownership of Kobu Railway, it offered electric trains from Iidabashi to Nakano, the first electric service in Japanese railway history.

Although trains run frequently in both Tokyo and Aichi, the mountainous portion of the Chuo Line is fairly quiet: between Shiojiri* and Nakatsugawa, trains only pass through every two hours or so. It's also important to note that there are no trains that cover the entire line in one trip: to travel the Chuo line, you have to transfer between trains several times. If you use rapid service trains, the entire trip from Tokyo to Nagoya takes about ten hours, compared to six hours on the Tokaido Line and as little as 100 minutes on the Nozomi Shinkansen.

The portions of the line that pass through the mountains offer some absolutely breathtaking views.

There are some faster limited express trains that run on the Chuo line, but they charge premiums over the normal fare. These include the Azusa from Shinjuku to Matsumoto, the Kaiji from Shinjuku to Kofu, and the Shinano from Nagoya to Nagano.

East of Shiojiri (just south of Matsumoto), the Chuo Line is administered by the East Japan Railway. West of Shiojiri, the Central Japan Railway takes over.

Within Tokyo, the line splits: there is a "rapid line," which only stops three times on its way from Tokyo Station to Shinjuku Station, and there is also a "local line" which stops at six additional stations. On the chart below, the local stations are denoted with parentheses. The line also splits between Okaya and Shiojiri: the shorter branch travels under a mountain, while the longer branch loops around to the south to serve a few more backwater stations.

Incidentally, the Chuo Line in Tokyo is also the most popular suicide spot in Japan, partly because it's one of the only straight surface-level lines in Tokyo, and partly because JR-East charges less cleanup fees to the family of the departed than other lines do.

Another Chûô line is part of the Osaka City Subway. It first opened in 1961 to connect the Osaka Loop Line to the Port of Osaka (Osakako): it was extended to the Midosuji Line in 1964, to the other side of the loop in 1967, to Fukaebashi in 1968, and to its current length in 1985. Some Chuo Line trains continue past Nagata to the Kintetsu network, going as far as Higashi-Osaka.

On maps, the Chuo Line is the green line (dark, not light; the yellowish-green line is the Nagahori Tsurumi Ryokuchi Line).
