Just when the high-speed rail was just put into operation, the minimum operating speed was not less than 200 kilometers per hour. The planning principle of the main passage of high-speed railway adopts the standard of 250km/h or above (it can be appropriately reduced in difficult areas with complex terrain, geology and climate conditions), and the railway with dense population and developed economy along the line and running through megacities can adopt the standard of 350 km/h. ..
Traveling by high-speed rail will be very safe, especially compared with buses and planes, so there is no need to worry about safety. Although the high-speed rail runs very fast, the braking distance is very short, about 4 kilometers. Even if there are some unexpected situations during riding the high-speed train, the high-speed train can brake successfully within 10 second, reducing the accident probability.
