Super Tokkyū

Last updated

Super Tokkyū (スーパー特急) is the name given to the concept of building new high-speed narrow gauge (1,067 mm (3 ft 6 in)) railway lines in Japan to extend the Shinkansen network of high-speed lines. [1]

No Super Tokkyū routes have actually been built.

Concept

The Super Tokkyū concept involves building new narrow-gauge lines along the routes of planned Shinkansen lines. All infrastructure would be built to high-speed Shinkansen standards, including its wider loading gauge, 4,000 m minimum curve radius, and total grade separation, with the ability to convert the lines to 1,435 mm (4 ft 8 12 in) standard gauge in the future. Although they would be slower than regular Shinkansen trains, they would have a speed of more than 200 km/h, enabling some reductions in journey times to be achieved, and total construction expenditure could be spread over a longer period, with travel times gradually reduced as more sections are completed. [1]

The ultimate goal is eventual conversion to standard-gauge Shinkansen track once the entire line is completed, but with gauge change trains (GCTs), it may be possible in the future to upgrade these sections to full Shinkansen specifications even while inter-operation with conventional lines remains in place.

Proposals

In 1991, the Super Tokkyū concept was formally planned to be used as part of the following three Shinkansen extensions: [1]

These schemes were subsequently constructed to full Shinkansen specification lines.

The West Kyushu Shinkansen route to Nagasaki was also initially proposed as a Super Tokkyū line from Takeo-Onsen. However, after construction commenced the proposal changed to incorporate GCTs, resulting in the Takeo Onsen to Nagasaki section (due to open in March 2023) being constructed as standard gauge lines. The service is proposed by GCTs using the Hakata to Shin-Tosu section of the Kyushu Shinkansen, then the narrow gauge line to Takeo Onsen, then the new West Kyushu Shinkansen line for the final section of the trip.

Shinkansen Japanese high-speed rail system

The Shinkansen, colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is operated by five Japan Railways Group companies.

Kyushu Shinkansen

The Kyushu Shinkansen is a Japanese high-speed railway line between the cities of Fukuoka and Kagoshima in Kyushu, running parallel to the existing Kagoshima Main Line and operated by JR Kyushu. It is an extension of the San'yō Shinkansen from Honshu. The southern 127 km (79 mi) was constructed first because the equivalent section of the former Kagoshima Main Line is single track, and thus a significant improvement in transit time was gained when this dual track section opened on 13 March 2004, despite the need for passengers to change to a Relay Tsubame narrow gauge train at Shin-Yatsushiro for the remainder of the journey to Hakata. The northern 130 km (81 mi) section opened on 12 March 2011, enabling through-services to Shin-Osaka.

The Hokuriku Shinkansen (北陸新幹線) is a high-speed shinkansen railway line jointly operated by East Japan Railway Company and West Japan Railway Company, connecting Tokyo with Kanazawa in the Hokuriku region of Japan. The first section, between Takasaki and Nagano in Nagano Prefecture, opened on 1 October 1997, originally called the Nagano Shinkansen (長野新幹線). The extension to Toyama in Toyama Prefecture and Kanazawa in Ishikawa Prefecture opened on 14 March 2015. Construction of a further section onward to Fukui and Tsuruga in Fukui Prefecture commenced in 2012, with scheduled opening in fiscal 2022. The route of the final section to Shin-Osaka was decided on 20 December 2016 as the Osaka–Kyoto route, with construction expected to begin in 2030 and take 15 years.
