The components of a steel rail
The components of steel rails can include the following aspects.
Rail head: The head of a steel rail is a protruding part of the upper part of the track, consisting of two sides and a top. Its shape is designed to guide the wheels of the train into the track and provide support and stability to ensure smooth operation of the train.
Rail waist: The waist of a steel rail is the main part of the track, usually with an I-shaped or H-shaped cross-section. It bears the weight and impact force of the train, disperses the train load, and maintains the stability of the railway.
Rail base: The foot of the steel rail contacts the railway track bed and is designed as a flat or convex base to accommodate different types of railway track beds. Its function is to support the track and fix the track position, reduce the gap between the track and the track bed, and improve the smoothness of train operation.
Other parts: In addition to the head, waist, and feet, the steel rail also includes connecting plates, bolts, washers, and other components. These components are used to enhance the connectivity and stability of the rails, ensuring the safety and reliability of the railway.

Meanwhile, different parts also play different roles
Rail head
The rail head is the part of the rail that directly contacts the wheel, mainly bearing the vertical pressure and lateral force of the wheel. It needs to have sufficient strength and wear resistance to ensure the smoothness and safety of train operation.
The shape of the rail head is designed as a circular arc to reduce friction between the wheel and the rail and provide minimal rolling resistance.
Rail waist
The rail waist is the part that connects the rail head and rail bottom, mainly bearing bending stress and shear stress. It needs to have sufficient bending strength and toughness to disperse pressure from the rail head and transmit it to the rail base.
The thickness and shape design of the rail waist directly affect the overall strength and stability of the rail.
Rail base
The rail bottom is the part where the steel rail contacts the rail sleeper, mainly transmitting pressure from the rail waist to the rail sleeper. It needs to have sufficient width and thickness to ensure even pressure distribution and prevent rail sinking.
The design of the rail base is usually flat bottomed or convex headed to accommodate different types of sleepers and fixing methods.
