I have been using delhi metro since last 6 years.
Previously travellers are less. But now a days number of travellers inctrasing so much.such that if you will travel on duty time that is at 9 Am in the morning, u will have to escape 2 to 3 metros if you are taking metro some what from the middle of the route. Fares are not more. And from last 10 days from when Odd even start, congestion in metro increases drastically.
