"Now one can book his train ticket 120 days before the journey as we have decided to provide an opportunity to the passenger to plan his journey four months in advance," said an official in the Commercial Department of Railway Ministry.
Centre for Railway Information System (CRIS) will make the necessary changes in the software for this purpose.
The four-month advance reservation period will also help those who travel during festivals or summer vacation period, he said. However, there will be no change in case of certain short distance trains like Taj Express and Gomti Express. "The advance reservation period for these trains are 15 days and it will remain unchanged," the official said.
There will also be no change in case of the limit of 360 days for foreign tourists.
Railways has earlier reduced the Tatkal booking period from 48 hours to 24 hours to prevent misuse of the facility.
