TheShinetsu Main Line (Japanese:信越本線,Hepburn:Shin'etsu-honsen) is a railway line, consisting of three geographically separated sections, operated by theEast Japan Railway Company (JR East) inJapan. It was originally one continuous line connectingTakasaki andNiigata viaNagano. Since the opening and later extension of theHokuriku Shinkansen, sections running in parallel have either been discontinued or transferred tothird-sector railway companies.

The name of the line refers to the old names for Nagano and Niigata prefectures,Shinano (Japanese:信濃), andEchigo (Japanese:越後).

The discontinued section through theUsui Pass was famous for its steep 66.7‰ (6.67%)gradient.^[1]

From 14 March 2015, the line consists of the following three sections.

• ■Takasaki –Yokokawa (29.7 km): inGunma Prefecture
• ■Shinonoi –Nagano (9.3 km): inNagano Prefecture
• ■Naoetsu –Niigata (136.3 km): inNiigata Prefecture

There are three small freight branches; from Echigo-Ishiyama Station to Niigata Freight Terminal, from Kami-Nuttari Junction to Nuttari Station (discontinued on 25 March 2010), and from Kami-Nuttari Junction to Higashi-Niigata-kō Station.

• Local: 1 or 2 trains per hour
• Excursion train:SL Gunma Yokokawa andSL YOGISHA Yokokawa (SL Gunma Yokokawa and SL YOGISHA Yokokawa [ja])

All trains run through on theShinonoi Line or theShinano Railway Line.

Limited express, Rapid

As of 3 May 2023^[update], the following services are operated.^[2][3]

Local

Naoetsu–Nagaoka: every 60–120 minutes

Nagaoka–Niitsu: every 60 minutes (every 20 minutes during peaks)

Niitsu–Niigata: every 20 minutes (every 5–10 minutes during peaks)

Excursion train (Joyful Train)

Koshino Shu*Kura

All stations are in Gunma Prefecture.

The section between Yokokawa andKaruizawa was closed and the section between Karuizawa and Shinonoi was transferred to the ownership of the third-sector railway operatorShinano Railway from 1 October 1997 with the opening of theHokuriku Shinkansen (Nagano Shinkansen) between Takasaki and Nagano.

All stations are in Nagano, Nagano Prefecture.

The section between Nagano and Naoetsu was transferred to the ownership of the third-sector railway operatorsShinano Railway andEchigo Tokimeki Railway from 14 March 2015 with the opening of theHokuriku Shinkansen extension north of Nagano.

All stations are in Niigata Prefecture.

TheJapanese Government Railways opened the Takasaki to Yokokawa section in 1885, the Naoetsu to Sekiyama section the following year, and the Sekiyama–Nagano–Karuizawa section in 1888. In order to surmount the 552 metre altitude difference between Yokokawa and Karuizawa (which are 10 km (6.2 mi) apart), it then constructed anAbtrack section through theUsui Pass, which opened in 1893, and was double-tracked for 1 km (0.62 mi) from Karuizawa to the top of the rack section. A horse-drawn tramway operated between Yokokawa and Karuizawa until the rack section opened.

The Hokuetsu Railway opened the Naoetsu to Nagaoka section in 1897, extending the line to Niigata in 1904. That company was nationalised in 1907. In 1909, the Imperial Japanese Railway authorities invited bids for the electrification of the route. A German company was selected to provide the engines andGeneral Electric supplied the turbines at the power station. In 1912, the rack section was electrified usingthird rail at 600 V DC, this being the first use of this method in Japan. The electrification allowed for the use of faster and longer trains which reduced journey times and also pollution from the steam engines.^[4]A link to archival footage of the rack section operation is available here

The Karuizawa to Nagano section was double-tracked between 1917 and 1920, with the Nagaoka to Miyauchi section double-tracked in 1931, and the Niitsu–Kamo section in 1944. Double-tracking of the remainder of the Niigata to Naoetsu line was undertaken in sections between 1958 and 1973.

Double-tracking of the remainder of the Takasaki to Kaminagano line was undertaken in sections between 1963 and 1973, commencing with the replacement of the rack mechanism with an adhesion only electrified (1,500 V DCcatenary) operation on the 1 in 15 (6.7%) grade. The rack equipment was initially kept as a contingency, and removed two months after the adhesion-only operation commenced and had proved its reliability.

The Kurohime to Myoko-Kogen section was double-tracked in conjunction with a realignment in 1980. The Mure to Kurohime section was also realigned and prepared for double-tracking (including new double-track size tunnels), but the second track was not laid.

The Miyauchi to Nagaoka section was electrified in 1947 at 1,500 V DC in conjunction with the electrification of theJoetsu Line, with the Nagaoka to Niigata section electrified in 1962, the same year the Takasaki to Yokokawa section was commissioned to facilitate the extension to Nagano the following year via the new adhesion line through the Usui Pass mentioned above. The Nagano to Naoetsu section was electrified in 1966, and extended to Miyauchi in 1969.

In 1997, following the opening of theNagano Shinkansen, the Yokokawa to Karuizawa section was closed, and the Karuizawa to Shinonoi section transferred to thethird-sectorShinano Railway.

On 14 March 2015, following the extension of theHokuriku Shinkansen toKanazawa, theNagano toNaoetsu section was also spun off to the following two third-sector operating companies owned primarily by the respective prefectures and municipalities.^[5]

• Shinano Railway Kita-Shinano Line (37.3 km,Nagano toMyōkō-Kōgen)
• Echigo Tokimeki Railway Myōkō Haneuma Line (37.7 km, Myōkō-Kōgen toNaoetsu)

Station numbering was introduced on the Shinonoi–Nagano section from February 2025, with Shinonoi station being assigned SE09. Numbers increase towards Nagano.^[6]

(Note - for the connections at stations between Karuizawa and Shinonoi, seeShinano Railway Line)

• Nagano Station: The Zenkoji Hakuba Railway Co. opened a 7 km (4.3 mi) line to Susohana Guchi in 1936. A proposal for the line to be extended to Hakuba on theOito Line did not eventuate, and the line closed in 1944.
• Kuroi Station: The Kubiki Railway Co. opened a 15 km (9.3 mi)762 mm (2 ft 6 in) gauge line to Uragawara between 1914 and 1916, with the line closing in 1971.
• Raikoji Station: The Nagaoka Railway Co. opened a 39 km (24 mi) line to Teradomari (on theEchigo Line) between 1915 and 1921. This company introduced Japan's first diesel railcar in 1928, and in 1951 electrified 31 km (19 mi) of the line at 750 V DC in 70 days, completing the balance the following year. Significant typhoon damage occurred in 1966, and in 1972, passenger services ceased between Raikoji and Nishinagaoka, with the entire line becoming freight-only three years later. The line closed in 1995.

The 13 km762 mm (2 ft 6 in) gauge Uonuma Railway to Nishiojiya was opened in 1911, and nationalised in 1922. It was converted to1,067 mm (3 ft 6 in) gauge in 1954, freight services ceased in 1960, and the line closed in 1984.

• Nagaoka Station: The Tochio Railway opened a 27 km762 mm (2 ft 6 in) gauge line to Tochio and Yūkyūzan between 1915 and 1924.^[7] The line was electrified at 600 V DC in 1948, with this being raised to 750 V DC in 1956. CTC signalling was commissioned in 1961, freight services ceased in 1967, and the line closed between 1973 and 1975.
• Higashi Sanjo Station: The Echigo Railway Co. opened the 8 km line to Echigo Nagasawa in 1927, and was nationalised two months later. Freight services ceased in 1960, and the line closed in 1985.
• Kamo Station: The Kanbara Railway Co. operated a line to Gosen on theBan'etsu West Line from 1923 until 2002.
