The Senseki Line (仙石線 Senseki-sen) is a railway line in Miyagi Prefecture, Japan, owned and operated by East Japan Railway Company (JR East). It connects Aoba-dōri Station in Sendai to Ishinomaki Station in Ishinomaki, and provides access to the central coast areas of Miyagi Prefecture, significantly the Matsushima area. It connects with the Sendai Subway Nanboku Line at Aoba-dōri Station; the Tōhoku Shinkansen, the Tōhoku Main Line and the Senzan Line at Sendai Station; and the Ishinomaki Line in Ishinomaki. The name Senseki (仙石) comes from the combination of the first kanji of Sendai (仙台) and Ishinomaki (石巻), the two cities that the Senseki Line connects.

Services
All trains originate from Aoba-dōri Station, with most running to Tagajō or Higashi-Shiogama. Local trains and rapid service trains that run the entire length of the line operate at 30-minute intervals. At Sendai Station, the line crosses under the Tōhoku Main Line and its platforms, similar to the situation with the Keiyō Line in Tokyo and the Chikuhi Line in Hakata (which connects via the Fukuoka Airport Subway Line).
The segment from Aoba-dōri to Higashi-Shiogama is a key part of Sendai's transportation system, and becomes very crowded during peak periods, and headways are as short as 4 minutes. During non-peak times 3-5 trains run per hour. Between Higashi-Shiogama and Ishinomaki two trains run per hour (generally one local and one rapid train).
In addition to all-stations "local" trains, there are two types of limited-stop "rapid" services on the Senseki Line. Both rapid services make only intermittent stops between Tagajō and Yamoto, but the first type (known as "green" rapids) stops at every station between Aoba-dōri and Tagajō, while the second type (known as "red" rapids) makes intermittent stops between Aoba-dōri and Tagajō. Local and rapid trains make all stops from Yamoto to Ishinomaki.
Green rapid trains serve Aoba-dōri, Sendai, Tagajō, Hon-Shiogama, Higashi-Shiogama, Matsushima-Kaigan, Takagimachi, Nobiru, Rikuzen-Ono, Yamoto, and all stations until Ishinomaki. Red rapid trains stop at the stations above as well as at all stations between Sendai and Tagajō.
A "Mangattan Train" operates on the Senseki Line, with a livery featuring Ishinomori Manga characters.
Service was halted since the 2011 Tōhoku earthquake and tsunami, as several trains, stations, and sections of the line were destroyed, heavily damaged, or flooded. Service for the first 16 miles of the line from Sendai was expected to be restored by the end of May 2011.[1] By mid-July, the Sendai – Matsushima-Kaigan and Yamoto – Ishinomaki sections had service restored, although the latter segment was with diesel trains due to the loss of the power substation.[2] As the remainder of the line between Matsushima-Kaigan and Yamoto was virtually obliterated by the tsunami.[2]
From March October 2012, services resumed on all but the Takagimachi to Rikuzen-Ono section,[3] with services on that section proposed to be restored by 2015, and a new 400m link is also due to be constructed from between Shiogama Station and Matsushima Station on the Tohoku Main Line to a point between Matsushima-Kaigan Station and Takagimachi Station on the Senseki Line. Costing approximately 2 billion yen to build, the new link will allow through-running services from the Tohoku Main Line to the Senseki Line, and cut approximately 10 minutes off the journey time between Sendai and Ishinomaki.[4]
Stations
(Stations in parentheses are currently not in operation due to damage from the March 11, 2011 earthquake and tsunami. Trains run on both sides of these stations, but as two unconnected lines.)

History
The Miyagi Electric Railway opened the line in sections between 1925 and 1928. Individual opening dates are given in the timeline section below. The Rikuzen-Haranomachi to Nishi-Shiogama section was double-tracked between 1968 and 1969, and extended to Higashi-Shiogama in 1981.
In 2000, the surface section between Rikuzen-Haranomachi and Sendai was replaced by a double-track underground line, with a new section to Aoba-dori to connect to the Sendai subway.
Parts of the line were extensively damaged by the 2011 Tohoku earthquake and tsunami, and whilst service was restored on the majority of the line by March 2012, the Takagimachi - Rikuzen-Ono section will not be returned to service until 2015.
