Rehabilitation of old and distressed railway bridges is an ongoing work on Indian Railways. A total number of 913 distressed railway bridges have been rehabilitated/ rebuilt/strength ened on Indian Railways since 2001-02 upto March, 2009. A total number of 48 distressed railway bridges exist on Indian Railways system as on 1st April 2009, out of which rehabilitation of three distressed bridges has been completed upto 31st May, 2009.
Certain bridges which may show signs of deterioration of physical condition indicating need for rehabilitation etc., are classified as distressed bridges. These, however, are neither unsafe nor dilapidated bridges. Priority is given to early rehabilitation/ rebuilding/ strengthening of distressed bridges. If required, suitable speed restrictions are imposed on such bridges till rehabilitation/ rebuilding/ strengthening is carried out. Sometimes, the bridges are strengthened due to the requirement of heavier axle loads and higher tractive effort. Based on such identification of bridges, allotment of funds is made annually to carry out their rehabilitation/ strengthening/ rebuilding duly prioritizing the works as per requirement.
Approximately 36,700 rail bridges on Indian Railway system are more than a century old. However, these bridges are safe for train operations. The work on bridges is undertaken on the basis of their physical condition as ascertained during regular inspections carried out in the field and not on the basis of age. Therefore, all old bridges do not necessary require rehabilitation.
