Train was invented in about 200 years ago. There are high speed train, regular train, light rail train, subway train and so on. Train give fast and comfortable riding and many other good things. However train cannot stop in a short distance when braking. This limits the safety and transportation volume. We got the patent technologies that can stop trains with only about 1/3 braking distance and greatly prevent derailing.  They are good for high speed train, regular train, light rail train, subway train and so on.  They give much high safety during driving in regular, curve, strong wind, earthquake. They can also double the present transportation volume of a railway.
