What are the three types of tracks?

In the world there are mainly three types of rail tracks, normal rail track, high speed rail track and subway track. In order to meeting the requirements of locomotive and transportation on the tracks, people designed various types of rail fastening systems relevantly.

• Normal railway fastening system

The designation of track for normal railway aims at slow and middle speed train for passengers or freights. The maximum speed of train is below 160km/h generally.

• High speed rail fastening system

The designation of track for high speed railway aims at very high speed train for only passenger.

• Subway rail fastening system

Subway, also named metro, the designation of its track aims at urban transportation for only passenger. The speed of subway is more than 100km/h.

What is a steel rail?

A steel rail is a specially shaped, heavy steel bar forming the track for trains, cranes, and other vehicles, providing a smooth, strong, load-bearing surface to guide wheels, withstand immense pressure, and transfer forces to sleepers, ensuring safe and efficient transport. Made from durable, high-carbon steel, these I-beam-like profiles have a head, web, and foot for optimal function, acting as a rolling surface and sometimes an electrical circuit.

Steel rail profiles consist of a head at the top. The web supports the head and is comparatively thinner. At the base of the component is the foot that rests on the track.

• Bullhead profiles feature equal cross sections at the head and foot of the item. The concept behind bullhead devices was intended to enable reuse. However, the actual design did not have the required symmetry to facilitate reusability and involved substantial construction and maintenance costs. Flat-bottom solutions replaced this construction.

• Flat-bottom rails or flanged T-rails in the North America feature a broader, flat foot at the base. This asymmetrical profile is now the most common product worldwide.

• Grooved rails have a troughed structure, or flangeway, at the head. The wheel flanges lie within the flangeway while the remaining part of the head is load bearing. Grooved rails are ideal for tramways presenting constraints on the space available to lay a dedicated rail track.

As a professional rail fastener supplier, GNEE RAIL can provide different standard steel rail such as American, BS, UIC, DIN, JIS, Australian and South Africa which used in railway lines, cranes and coal mining.
