The difference between first-class and second-class high-speed rail is
1. The first-class seat is more spacious than the second-class seat. The seats in the second-class seat are narrow between rows and aisles, which makes it crowded and dull.
2. There are fewer first-class seats than second-class seats. There are 4 seats in a row of first-class seats, 2 seats on one side, and 5 seats in a row of second-class seats, 2 seats on one side and 3 seats on the other side.
3. The price of a first-class high-speed rail seat is generally tens to hundreds of yuan more expensive than the corresponding second-class seat. The price of second-class seats is relatively low and economical.
The first formal high-speed railway system in the world is Japan's Tokaido Shinkansen, which was completed and opened to traffic in 1964, connecting the three metropolitan areas of Japan where Tokyo, Nagoya and Osaka are located, and promoting Japan's high-speed development. Its design speed is 200km / h, so the initial speed standard of high-speed railway is 200km / h.
Therefore, the initial speed standard of high-speed railway is 200km / h. Later, with the progress of technology, the train speed was faster. Different countries in different times had different definitions of high-speed railway.
In the code for design of high speed railway issued by the State Railway Administration of China, high speed railway is defined as a new passenger dedicated railway with a design speed of 250 km (inclusive) to 350 km (inclusive) and a standard gauge for running EMU trains.
China's national development and Reform Commission defines China's high-speed railway as a new line or existing line with a speed of 250 km / h or above, and has issued the corresponding medium and long term railway network planning document to include some track lines with a speed of 200 km / h into the scope of China's high-speed railway network.
