Before the invention of continuous welded rail (CWR), traditional railway tracks are lengths of rails joined by rail joints (joint bars, fishplate). If you look closely at the rails, you will find that every certain distance, that is more than 12 or 24 meters, there will be a small gap between the two rails. It …
Made of steel, railway track (railroad track in AE) will expand when the temperature rises and contract when it’s cold. When the railway track is exposed to extreme heat, it may buckle. When the ground temperature reaches 37℃, the rail surface temperature can reach about 50℃. Due to the principle of thermal expansion and contraction …
Railway steel or some called rail steel is used for making railroad tracks. Railroad tracks are bearing heavy loads and subject to wear and fatigue. So the grade of railway steel must meet the demands of train speed and load. Proper chemical composition of railway steel enables the rails to have enough hardness and wear …
A railroad frog is a device that helps the wheels rolling from one track to another. It is also called the “common crossing”. As a part of the railroad switch, it takes the area where two rails cross. Crossing nose and wing rails are main parts of the frog. To understand how the railroad frog …
The railway track is a British express of the tracks on a railway. It is also called railroad track in the United States. Usually, people talk about the railway track as a whole structure including rails, sleepers, fasteners, ballast (or slab track ) and subgrade. The structure can be divided into two parts, the superstructure …
Railroad tracks, also called railroad rails or railway tracks, are essential for railway systems for its function of leading trains move forward and carrying loads then transfer it to the lower structure. With the development of railways in the direction of high-speed and heavy-load, modern requirements for rail quality are getting higher and higher. As …
As we all know, railroad tracks are produced with certain lengths, such as 12.5m, 25m, and the lengthen ones from 50m to 100m. No matter how long the railroad rail is, they need to be joined end to end to make a continuous railroad. This can be realized by rail joints (joint bars) or welding …
In railroad transportation, railroad tracks support and lead the locomotives to move forward. If the tracks crack, the trains may derail or turn over which will cause serious damage to people’s lives and property. Railroad track inspection is the process of using non-destructive testing (NDT) methods to detect rails in a planned way to find …
Railway track gauge is the distance between the inner faces of the head of two rails. You might be wondering what different types of gauges are currently found around the world? About 60% of the world’s railroad tracks use the standard 1435mm (4 ft 8 1⁄2 in) gauge today. The other 40% use either a narrow gauge or a …
How many types of railway tracks are there in the world? Probably more than you think. Types of railway tracks can be divided from different aspects such as the rail gauge, the construction form, etc. Railway tracks with different rail gauges Rail gauge is the distance between the rails of a railroad track or the …
