History
The line owes its existence to the construction of the Tōhoku and Jōetsu Shinkansen. The branch point of the two high-speed lines was set in the town of Ina, and residents there opposed the project, arguing that the new viaduct would divide the town and bring noise pollution. To compensate the affected communities of Ageo, Ina and the former city of Ōmiya, a new urban railway was promised. Where the residents of Toda and the former Urawa and Yono — who had likewise opposed the Shinkansen — were given the conventional heavy-rail Saikyō Line, the corridor north of Ōmiya was judged to lack the demand to justify an ordinary railway, so the medium-capacity AGT system then being built in many parts of Japan was adopted instead.
The entire line is elevated and laid alongside the Tōhoku and Jōetsu Shinkansen viaduct, sharing the same piers along most of its length; the double-track section flanks both sides of the Shinkansen viaduct, while the single-track section runs along the western side of the Jōetsu Shinkansen. The line was built by the Japan Railway Construction Public Corporation. At the Ōmiya terminus trains reverse around a loop, whereas at Uchijuku and at Maruyama, where the depot is located, they reverse conventionally, so a train's orientation alternates with each round trip — a distinctive feature of the operation.
A licence to operate a local railway was applied for on 4 December 1980 and granted on 3 April 1981, and civil-engineering work on the Ōmiya–Hanuki section began that October. The route's nickname was put to a public competition, which drew 613 entries, but the names ranked highest in the preliminary review were not adopted. After an internal review, the operator chose "New Shuttle" on 22 July 1983. The name combines "new" with "shuttle", a word often used for round-trip transport, and, inspired by the Space Shuttle, stands for a new system of short-distance round-trip trains. The first section, from Ōmiya to Hanuki, opened on 22 December 1983, with rubber-tyred trains of the 1000 series (later 1010 series); about half of all trains ran only as far as Maruyama, and beyond Maruyama service was every forty minutes during the day.
The planned extension from Hanuki to Uchijuku stalled because land negotiations with two property owners along the route broke down, so the 1983 opening reached only as far as Hanuki. One owner settled in March 1988, but talks with the last holdout became badly tangled after Chūkaku-ha activists, claiming to support the owner, intervened. On 17 February 1990 Saitama Prefecture carried out an administrative execution under the Land Expropriation Act; the owner and the activists barricaded themselves in a hut and protested, and were eventually arrested, after which the air rights over the owner's property were expropriated to carry the elevated track over it.
The remaining Hanuki–Uchijuku section finally opened on 2 August 1990, completing the line, and the new 1050 series six-car trains brought the fleet to ten sets, later increased to thirteen. By 1 October 1992 every train on the line had been lengthened to six cars. Since opening, large apartment blocks, shopping centres and new-town development have driven a continuous rise in the lineside population.
On 18 March 2007 the Suica IC card was introduced, and on 14 October 2007 Ōnari Station was renamed Tetsudō-Hakubutsukan ("Railway Museum") Station when the Railway Museum opened beside it, making the New Shuttle the principal access route to the museum; station colours were also assigned at the same time. Station numbering using the prefix "NS" was introduced on 23 March 2018. The 2020 series trains, built by Mitsubishi Heavy Industries, entered service from 4 November 2015, and the long-serving 1050 series made its final run on 15 February 2026.
