Senior citizens, women above 45,and pregnant women can now book up to 4 lower berths in sleeper class

Passengers used to complain that if senior citizens husband and wife wanted to book 2 lower berths, they were denied as they were travelling together.
With the new rule,if up to 4 persons make a single booking and all were senior citizens or women above 45 or pregnant,any of these combination, then each would get lower berth in sleeper class.
