The future of Japan's Shinkansen: Why did the E7 and W7 series amaze the world?
Japan's Shinkansen system has been constantly evolving as technology advances and transportation needs change. The E7 and W7 series are high-speed electric trains developed for the Hokuriku and Joetsu Shinkansen lines, and have been the preferred choice for transporting trains since 2014 and 2015. These two series not only improve transportation efficiency, but also attract the world's attention with their unique design and strict requirements on quality.
Design concept and appearance
The design of the E7 and W7 series trains combines traditional and modern Japanese elements, presenting a futuristic style both inside and outside. Under the direction of industrial designer Ken Okuyama, the trains feature a "sky blue" roof and "ivory white" sides, with copper and sky blue stripes, making them unique and easily recognizable.
“The design of the E7 and W7 series is not only about improving passenger comfort, but also about the pursuit of harmony and beauty.”
Performance and Operations
The E7 and W7 series trains are designed to reach speeds of 275 km/h (170 mph), however the actual maximum speed on the Hokuriku Shinkansen is 260 km/h (160 mph) and on the Joetsu Shinkansen is limited to 200 km/h (160 mph). at 240 km/h (150 mph). These trains redefined the concept of speed on steep grades, capable of operating at a steady 210 km/h (130 mph). In addition, the trains are equipped with a fully active suspension system to further enhance ride comfort.
Operation Status
Since 2014, the E7 series has been operating on several major routes, including the Asama service from Tokyo to Nagano and the Tsurugi service from Tokyo to Toyama. In contrast, the W7 series began operating in 2015 and has increased its services to international passengers, especially during the winter operation period for activities such as skiing.
"The emergence of the E7 and W7 series marks the beginning of a new era for Japan's Shinkansen."
In-car facilities and customer experience
The interior design of the E7 and W7 series trains takes into account the various needs of passengers, providing three different service levels: Gran Class, Green Car and Ordinary Car, with a total capacity of 934 passengers. Each seat is equipped with an AC power socket and the carriage is equipped with surveillance cameras to ensure passenger safety.
Construction and historical background
The E7 and W7 series were jointly developed by East Japan Railway Company and West Japan Railway Company respectively, and the birth of the series was based on patient testing and continuous improvement. Since being put into use in 2014, these trains have withstood various tests, including the unfortunate typhoon disaster.
Challenges and the future
Although the E7 and W7 series have demonstrated their superiority in their respective operations, there is still a long way to go before they can challenge autonomous driving and higher-speed operation. JR East demonstrated autonomous driving of the E7 train in 2021, but it will still take time and technological breakthroughs to popularize this technology across the entire line.
"Whether the future Shinkansen will become a driverless means of transportation will be an important factor affecting its development."
Japan's Shinkansen system is always seeking innovation to meet future needs. The success of the E7 and W7 series is not only a technological achievement, but also a movement leading global transportation. In the future, we may see more innovations that surpass current achievements, which makes us wonder: what will our travel look like as new technologies emerge?
