Narita Line

The Narita Line (成田線) is the name for a combination of three railway lines located in Chiba Prefecture, Japan, operated by the East Japan Railway Company (JR East).

The main line connects Sakura Station and Matsugishi Station (as an alternate route to the Sōbu Main Line), and is sometimes referred to as the Samatsu Line (佐松線). A branch line from Abiko Station to Narita Station is often called the Abiko Line (我孫子線), and a second branch, known as the Airport Line (空港線) connects Narita to Narita Airport Terminal 1 Station. The first two lines are owned and operated by JR East; the Airport Line is owned by a separate company, Narita Airport Rapid Railway, which allows JR East and Keisei Railway to use the line for passenger services.

History
The Sakura - Narita - Namegawa section of the line was opened on 19 January 1897, by Sobu Railway, extended to Sawara the following year. The Narita to Abiko branch opened in 1901. The company was nationalised in 1920, and the Sawara to Matsugishi section opened between 1931 and 1933.

The Sakura to Narita section was electrified (at 1,500 V DC overhead) in 1968. The Abiko branch was electrified from 1 October 1973. The Narita to Matsugishi section was electrified in 1974, and freight services ceased between 1984 and 1986.

The Sakura to Narita section was double-tracked in 1986, and the Airport branch opened in 1991 as an electrified, CTC-signalled line.

Accidents
In the early hours of 10 March 2011, a day before 2011 Tōhoku earthquake and tsunami occurred, a freight train carrying ethylene oxide derailed and overturned on the Narita Line near Namegawa Station.
