Indian Railways have planned to extend the useful life of a large number of arch bridges by about 25 years by adopting techniques in collaboration with International Union of Railways (UIC).
There are a large number of arch bridges on Indian Railways. Several bridge improvement and rehabilitation measures have already been undertaken in the recent past.
Besides, Indian Railways are interacting with various Indian Institutes of Technology and premier research institutes in the country and abroad and Advanced Railway Systems in the field of Bridge Engineering. It has been planned to take up research and development projects in areas of protection from earthquake and rehabilitation of bridges, residual life analysis for concrete and masonry bridges, high performance concrete and corrosion protection systems for bridges.
The Railways have 120,000 bridges across the country.
