不停站可上下乘客的火车（Non-stop passenger train） My answer: After this video posted on the received many questions, in order to make the science and engineering are also can understand, so I will answer you in one of the most popular language, first there is you can see the animation is made of the train was traveling at 200 kilometers an hour, every second past two trunk, trunk per day 26.5 meters long, 1 g acceleration Can the huge acceleration of a moving carriage endure? Answer: my design flow carriage will with 1 g (1 acceleration of gravity) = 9.8 m/s ^ 2 for acceleration and deceleration, every one of us are in a given by the force of gravity acceleration, thus acceleration acceleration, chair back thrust for you just be your self-respect, that is to say, the stress of the flow when the car speed up your back and back stress when you lie on the bed feeling is the same, this feeling should be all they can afford to per capita (including critically ill patients can sit), below to take the train to speed 200 km / = 55.6 m/s through the station, so the time needed for acceleration or deceleration of carriage is 55.6/9.8 = 5.67 seconds, the acceleration and deceleration the distance needed for the s = 1/2 the at ^ 2 ^ 2 = 0.5 * 9.8 * 0.5 = 157.48 m, so as long as the train and the length of the platform frame are more than 300 meters that will be very safe, and now the train every day length is about 26.5 meters, if its length with 12 cars will be 26.5 * 12 = 318 meters, due to the constant solution as long as the same passenger station can be up and down passengers can take the same train, so even if will be 20 cars together wont lack of passengers, the platform framework built 500 meters long is the simple things. In addition, if you look at the speed of the plane at a speed of hundreds of kilometers per hour in a few seconds, all of these are superfluous. In fact, even if you control the braking distance to 80 meters, you will feel very good, because the average person c
