Indian Railways will replace traditional sleepers with advanced composite sleepers on steel girder bridges. These new sleepers are made from recycled plastic, rubber, and synthetic materials. This move will allow trains to travel at speeds of 160 km/h without jerks, improving both safety and ride quality.

What are composite sleepers and their benefits?
Composite sleepers are lightweight yet strong alternatives to concrete or wood. They can handle heavy axle loads of up to 25 tons and withstand pressure up to 700 kg per square centimeter. These sleepers are fire-retardant, weather-resistant, and have a minimum service life of 35 years, which will reduce the need for frequent maintenance.
Who is implementing this project and how?
The project follows review meetings led by Railway Minister Ashwini Vaishnaw. On June 4, 2026, Anurag Kumar, Executive Director (Track Modification), directed all railway zones to identify bridges for the first phase. The RDSO has approved the technology and will inspect the first 100 sleepers supplied.

What other safety measures are being added?
Along with the new sleepers, Indian Railways will use AI-based track monitoring. This includes Ground Penetration Radar (GPR) to find subsurface issues and Magnetic Particle Testing to detect tiny defects in welded rail joints. These technologies will work together to make train travel more reliable.
