With the increase in rail traffic and faster train speeds, railroads around the world are turning to composite sleepers as their advantages become increasingly apparent. Also, with the weight per car increasing and the availability of older hardwoods decreasing dramatically, the use of composite sleepers has also seen a tremendous growth trajectory.
Due to their composition, these sleepers can be recycled, as recognised by railway authorities. Although their functional properties are similar to wooden sleepers, they are not subject to corrosion and, as they are self-insulating, do not require insulation. Composite sleepers have fewer parts than steel channel sleepers, making inspection and maintenance easier. Composite sleepers also do not need to be painted and have the added benefit of reducing noise pollution due to the product's natural damping effect.

With an expected lifespan of over 40 years, composite sleepers outperform wooden sleepers due to the use of recycled materials like HDPE, filled rubber, fiberglass reinforcements and fillers. Moreover, these sleepers are less prone to cracking, rotting or insect damage and are easy to maintain, reducing the overall operating cost of Indian Railways.
Composite sleepers are environmentally friendly as it controls deforestation, helps reduce noise pollution and provides 100% sound insulation. Even its fasteners are similar to wooden sleepers. One of the biggest advantages of these sleepers is that it is 40% cheaper than the steel channel sleepers used in beam bridges.
