It is on several online newspapers that starting from Dec 31, 2013, train passengers are able to buy tickets online and via the phone up to 20 days ahead of their preferred departure time.
The new rules give passengers 8 extra days to book the tickets. Previously, passengers were only able to book tickets 12 days in advance.
