秋田新幹線の未来【新仙岩トンネル・空港新線・奥羽新幹線を一挙解説】

This time, we will examine the future of the Akita Shinkansen based on online resources from JR East and related local governments, materials from the Japan Society of Civil Engineers Tohoku Branch Technical Research Presentation, and information from Wikipedia. The Akita Shinkansen connects Tokyo to Akita. The Tazawako Line and Ou Main Line between Morioka and Akita were improved to allow direct Shinkansen trains, and the line opened in 1997 as a mini-shinkansen (a new line/local line direct connection system) that is not governed by the Nationwide Shinkansen Railway Development Act. The act defines a Shinkansen as "a main railway capable of running at speeds of 200 km/h or more on its main sections." Legally, the section between Morioka Station and Akita Station is a conventional line, not a Shinkansen. The Tohoku Shinkansen operates at a maximum speed of 320 km/h between Tokyo Station and Morioka Station, but the section from Morioka Station to Omagari Station and Akita Station is a conventional line, so the maximum speed is 130 km/h. Additionally, due to wiring arrangements, a switchback is performed at Omagari Station. In 2014, all of the trains were replaced with E6 series trains for direct Shinkansen/local service, and the "Komachi" train operates 15 round trips per day. This article summarizes efforts to enhance the Akita Shinkansen's functionality. Conclusion The Akita Shinkansen faces issues such as route constraints and aging, and improvements are needed. There are efforts to enhance functionality, such as the construction of the Shin-Sengaku Tunnel, a new line directly connecting to the airport, and consideration of the Ou Shinkansen.
