The 12.7-kilometre Ina Line (伊奈線 Ina-sen?) that runs north from Ōmiya Station in Saitama, Saitama, along Jōetsu Shinkansen through Ageo to Uchijuku Station in Ina in Saitama Prefecture in the Greater Tokyo Area is the only route that is run on the system. The line is double tracked from Ōmiya Station to Maruyama Station and single tracked from Maruyama to Uchijuku Station.
The line is operated by Saitama New Urban Transit Co., Ltd. (埼玉新都市交通株式会社 Saitama Shin Toshi Kōtsū Kabushiki-gaisha?), a kabushiki gaisha whose major shareholders include the East Japan Railway Company, Tobu Railway, banks, Saitama prefectural government and the cities and the town served.

The people of Ina town, on the branch point of the Tōhoku and Jōetsu Shinkansen high-speed railway lines, opposed the latter being routed through their area, complaining that the town would be divided by the new tracks and beset with noise pollution.
To placate the residents, new railway lines were planned. The AGT Ina Line was the solution reached for the area north of Ōmiya Station, where the potential demand was not large enough to run heavy rail lines economically. (Currently, the line generates an operating profit.) A heavy rail line (the Saikyō Line) was the solution reached for the south of Ōmiya Station.
