The shape of the steel rail

The shape of the steel rail is an "I" shape. This shape of steel rail consists of three parts: rail head, rail waist, and rail bottom, forming a wide bottomed "I" - shaped cross-section, which constitutes the steel rail. The steel rail consists of three parts: the rail head, the rail waist, and the rail bottom. The rail head matches the wheel rim, and this design of the steel rail can perfectly embed into the wheel rim to ensure smooth operation of the train; The rail base is wide and has a large force bearing area, which can withstand enormous pressure and transmit it to the rail sleeper.
 

Steel Rails

Steel rails are an important part of railway transportation. The steel rails used in modern times are cut in an "I" shape, divided into a rail head in contact with the wheels, a middle rail waist, and a bottom rail bottom. Different routes have different requirements for the strength, stability, and wear resistance of steel rails. Therefore, steel rails also have different specifications. Which route should be chosen based on economic and technological factors.

The type and strength of steel rails are expressed in kg/m. The heavier the steel rail per meter, the greater the weight it can bear.

The common rail weights in European railways are as follows:40kg/m ,50kg/m, 60kg/m.
China has: 50kg/m ,60kg/m ,75kg/m.

The main lines use 60kg/m or 75kg/m steel rails.The steel rails used in the United States are heavier, with some coal transportation lines weighing up to 77kg/m.
