A maglev bullet train that can reach speeds of 600 kilometers per hour (373 miles per hour) has made its debut in Qingdao, China. Developed by the state-owned China Railway Rolling Stock Corporation, it’s considered the world’s fastest train.
“Maglev” is an abbreviation of “magnetic levitation.” The train appears to be “floating” thanks to an electromagnetic force that sends it gliding above the tracks.
Liang Jianying, deputy general manager and chief engineer of CRRC Sifang, told Chinese state media that in addition to its speed, the train emits low levels of noise pollution and requires less maintenance than other high-speed trains.
“emits low levels of noise pollution”で「低レベルの騒音公害を排出する」と言っていますので、「ほとんど騒音公害が出ない」という意味。
また、”requires less maintenance than other high-speed trains”なので、「ほかの高速鉄道より少ないメンテナンスを要求する」ということから、「メンテナンスが少なくて済む」という訳に結びつきます。
何となく、わかるような気がします。
浮いているので、騒音は発生しそうにないですね。
メンテナンスが少なくて済むのは、稼働部分が少ないからでしょうか?
でも、電磁波とか体に悪そうな影響も全くないとは限らないような気がします。
A prototype of the new maglev train was revealed to media in 2019. That same year, China announced ambitious plans to create “3-hour transportation circles” between major metropolitan areas.
High-speed rail is a major priority in China, which aims to connect more of its large cities by train to reduce the time and expense required to travel around the world’s most populous country.
世界で最も人口の多い国を旅行するのに必要な時間と費用(the time and expense required)を削減することが目的。
中国では、春節などに国内をたくさんの人が移動するのがニュースになっていますよね。
それで利用されるのが列車が多い。
だから、高速鉄道の整備が最優先事項なんですね。
Currently, the average high-speed train in China can run at about 350 kph, while planes fly at 800-900 kph. Trains like the one unveiled in Qingdao this week could fill a critical middle space.
Currently, China only has one maglev line in commercial use, connecting Shanghai’s Pudong Airport with the Longyang Road station in the city. The 30 km (19 mile) journey takes about seven and a half minutes, with the train hitting speeds of 430 kph (267 mph).
Several new maglev networks are reportedly under construction, including one linking Shanghai and Hangzhou and another connecting Chengdu and Chongqing.
