Types of Wood Railway Sleepers: sleepers are a kind of railway accessories, which play an important role in railway construction. There are three types of sleepers: Wood Railway Sleepers, steel sleepers and concrete sleepers. Let's learn more about the relevant knowledge of sleepers for railway accessories.

Wood Railway Sleeper is one of the sleepers for railway fittings, which has the advantages of good elasticity, easy processing and convenient to use. Since the railway, Wood Railway Sleeper is the main type of sleeper. However, due to the reason of taking materials, the elasticity, strength and durability of Wood Railway Sleepers are not uniform enough, which will increase the wheel rail dynamic effect, and use a large number of high-quality wood. The service life of wooden pillow is short, and there are many reasons for its failure, such as decay, mechanical wear and cracking. Compared with other railway fittings, Wood Railway Sleepers are easy to rot, so they need to be treated with anti-corrosion before going on the track. Wood Railway Sleepers without anti-corrosion treatment are called plain sleepers.

The advantages are anti-corrosion, anti termite and moth; the disadvantages are chemical corrosion, non insulation, high maintenance cost. Stainless steel sleepers are only used in some railways in Germany and Switzerland, and in some railways in the tropics, but not in China.
