In the case of Senior citizens, no proof of age is required at the time of purchasing tickets. Concession tickets are issued on demand made through the option in reservation form. However, they are required to carry some documentary proof showing their age or date of birth and produce it if demanded by some Railway Official during the journey. Any document issued by any Government Institution/ Agency/Local Body, like Identity Card, Ration Card, Driving Licence, Pass Port, Educational certificate, certificate from Panchayat/Corporation/ Municipality, or any other authentic & recognised document, is acceptable for this purpose. The Pass Port issued by foreign countries is also valid.
