Do you know how the E7 series can maintain super high speed on steep slopes?
Did you know? In Japan's high-speed rail system, the E7 series and W7 series Shinkansen are famous for their outstanding performance, especially their ability to maintain ultra-high speeds on steep slopes. These trains are not only symbols of time, but also examples of engineering and design, demonstrating how advanced technology can be used to solve practical problems in extremely challenging environments.
“The E7 and W7 series Shinkansen combine modern and traditional elements in design, allowing passengers to experience not only high speed and comfort, but also Japanese aesthetics.”
Design and Technology
The E7 series has been operating on the Hokuriku Shinkansen since 2014 and was added to the Joetsu Shinkansen in 2019. The design of these trains is inspired by the previous E2 series, and the appearance was designed by industrial designers to fully reflect the "Japanese" theme. The train's exterior is dominated by a "sky blue" roof and an "ivory white" body, with "copper" and "sky blue" stripes, showcasing a modern aesthetic.
Its maximum design speed is 275 kilometers per hour, but on the Hokuriku Shinkansen, the actual operating speed is 260 kilometers per hour, and on the Joetsu Shinkansen it is limited to 240 kilometers per hour. In addition, these trains can still maintain a speed of 210 kilometers per hour on routes with steep gradients, thanks to the enhanced power output design.
“The train’s powertrain and suspension systems are key to the design, allowing us to operate safely on steeper slopes.”
Various operating services
The E7 series has different train service types, including "Kuki", "Shirataka" and "Goriki". These services are not limited to the main route between Tokyo and Kanazawa, but include the four main commuter services. Interestingly, since their introduction, these trains have gradually become the main transportation option along with the extension of the Hokuriku Shinkansen, especially favored by passengers during the winter travel season.
“With the arrival of the winter ski season, the demand for trains such as the "Kuki" has increased significantly, providing a comfortable travel experience. ”
Interior Facilities and Passenger Experience
The E7 series trains offer three different service levels, including Gran Class, Green Car and Ordinary Car, with a total of 934 seats. The seats provided in Gran Class are designed with great care to ensure maximum comfort for passengers. The train is also equipped with power sockets and security monitoring systems to ensure the needs and safety of passengers.
In the future, to cater for the growing number of international passengers, these trains will also add luggage racks in some ordinary carriages so that passengers can carry items such as ski equipment. This change will strive to improve passenger convenience.
Conclusion
With the continued operation of the E7 and W7 series Shinkansen, they have not only set industry benchmarks in terms of speed and comfort, but also continued to innovate in design and technology. How will these Shinkansen lines further improve passenger experience and safety in the future?
