New Delhi: Railways has decided to replace wooden sleepers with composite sleepers that are not only lighter but also stronger. A senior Railways official said,“The Railways has decided to use the composite sleepers in a limited way. It is being used mainly on girder bridges.”
- Composite sleepers were first used by the Indian Railways in the Muradabad division in 2003.
- No complaint has been received till date about the use of these sleepers, which were deployed on a bigger scale from 2016 in over 10 zones, the official said.
- The Railways preferred them over wooden sleepers because of environmental issues that cropped up over the cutting of trees, he said.
- “This decision has been taken in the wake of a Supreme Court order imposing restrictions on cutting trees. If successful, all wooden sleepers will be replaced with composite sleepers.”
- In June 2016, the Railway Board Executive Director (Track), in a letter to all the zonal offices, said that the RDSO (Research Designs & Standards Organisation) was planning to replace wooden sleepers with those made of composite material.
- It would initially be tried on bridges.
- The primary function of a sleeper is to grip the rail to the gauge and to distribute the rail load to ballast with acceptable induced pressure.
