The design for concrete sleepers had been constantly undergoing change in conjunction with the R&D of Bangladesh Railways to suit the changing requirements. With the adoption of finest grade cement, the life of these sleepers increased. With the base width increased, the ballast pressure came down by 10% leading to proportionate savings on ballast and maintenance costs.
The company manufactures these prestressed concrete (PSC) sleepers in its own factory over 8.72 acres land with thousands of employees with a total installed capacity of 2,00,000 sleepers per annum.Bangladesh Railways has plans to go for higher axle loads in coming years and the new design for concrete sleepers will suit future requirements of the railways. The company also envisages the use of special strand wire with higher UTS by which the overall weight of steel per sleepers will be brought down by 25%.
