How much do you know about steel rail sleeper?

On the railroad construction, wood rail sleeper, steel rail sleeper and concrete rail sleeper are the three most common rail sleepers. Tracing the source, rail sleeper originates from wooden sleeper. In the past 100 years, wood rail sleepers are the most widely rail sleepers in railroad, especially in heavy rail and bridge rail. With the development and technical requirements of railroad construction, rail sleepers are now made of varieties materials, such as steel, concrete and rubber. Today, I will show you around the world of steel rail sleeper and get you to know more about the features.

Steel rail sleepers are often seen as a middle ground between wood and concrete. Sturdier than wood and less expensive than pre-stressed concrete, it seemed logical that steel could prove a boon to companies looking to undertake an economical track upgrade. Indeed, in some areas steel ties are still performing adequately after 50 years of service. A lesser reliance on ballast (approximately 60% less than required for concrete; 45% less than wood) also seems to tip the scale in steel's favors, especially in areas where timber is scarce.

Advantages of steel rail sleepers

• Longer lifespan (30-40 years)
• Ensure the smooth of railway transportation

Disadvantages of steel rail sleepers

• Corrosion prone
• Unsuitable for track circuiting areas
• Develops cracks at rail seats
