Are The Rails Of The Railway Steel Rails Or Iron Rails

On busy railway lines, trains roar past, sending passengers and goods to all parts of the country. However, have you ever wondered how these trains can run smoothly on the railway? The answer lies in those seemingly simple but crucial tracks. But the question is, are the rails on these tracks "steel rails" or "iron rails"? Today we will uncover this mystery.

First, let's start with the material of the track. Early railway tracks were indeed made of iron. Although these rails could bear the weight of the train, their strength and wear resistance were relatively poor, and they were easily worn and deformed. With the advancement of technology and the improvement of materials, people began to use steel to make tracks, which is what we now call "steel rails".

There is a clear difference between steel rails and iron rails in terms of material. Steel rails are mainly made of high-quality steel, and their strength and wear resistance are much higher than iron rails. This allows steel rails to withstand greater weight and higher operating speeds, while reducing wear and maintenance costs. Therefore, modern railway systems generally use steel rails to ensure the safety and efficient operation of trains.

In addition to the material, there are many ways to classify steel rails. According to the unit weight, we can divide rails into heavy rails and light rails. In my country, rails of 50kg/m and above are called heavy rails, such as 50kg/m, 60kg/m, etc., while those below 50kg/m are called light rails. These rails of different weights are suitable for different railway lines and train types to meet different transportation needs.

Rails can also be classified according to their cross-sectional shapes. The most common cross-sectional shape of rails is I-shaped, which consists of three parts: the rail head, the rail waist, and the rail bottom. This shape has good stress resistance, saves materials, and has the best bending resistance. At the same time, there are also asymmetric cross-sectional rails, which are mainly used to make complex parts such as turnout point rails and fork rails.

Are rails steel rails or iron rails? The answer is obviously steel rails. Although iron rails were used in history, modern railway systems generally use steel rails to ensure the safe and efficient operation of trains. Steel rails have become a key component of railway systems due to their high strength, wear resistance and good bending resistance.
