Shinkansen: Shinkansen is designed to be suitable for fast and large-scale transportation at the same time, so its construction and operation technology is different from that of traditional railways, for example, it is completely powered by decentralized trains, and the track is completely equipped with interchange and automatic train control system. , it can run for at least 3 minutes. Except for the mini Shinkansen, the maximum speed of the train can reach 240-320 kilometers depending on the line, but in the speed test, it once set a record of 443 kilometers (set by the "300X" experimental train of 1996). Shinkansen technology, as an important symbol of Japan's top railway technology in the world, has also been exported overseas. For example, Chinese mainland's high-speed rail technology and Taiwan Province's high-speed rail adopt Shinkansen as the system foundation, while Britain, Italy, India, Thailand and Texas are also under construction or planning.
