Principle introduction:

The bogie of the train is stuck on the track and runs along it. When turning, the bogie rotates to keep the train running along the track. When turning, the outer rail is higher than the inner rail. The original trains were drawn by ropes or horses. By the19th century, most trains were pulled by steam locomotives. After the 1940s, steam locomotives were gradually replaced by cleaner and more labor-saving diesel locomotives.

The initial investment of electrified railway is large, but the operating cost per mile is the lowest, so only large-flow lines are suitable for electrification. Electrified trains may use overhead cables or the third rail to obtain electricity. Calculating the efficiency of locomotive head by dividing the unit kilowatt power by the weight metric tons that can be towed is called the traction capacity ratio, and the efficiency of steam locomotive is the lowest.
