I am a Hyderabadi . I visited delhi in last December . As soon as I landed in delhi the first thing I experienced was the traffic . It took me almost 90 minutes to get to my destination in delhi. Soon after we got fresh we had to go to Gurgaon . And the best way and the fastest way to go to Gurgaon was to take the metro. We were like okay lets go in the metro. And I have never experienced something like this before in india. We took the tickets and we went up to the platform and one train just left . So we were thinking that it might take couple of minutes for the next train tp come so we started waiting but the next train came almost 3 minutes later . and trust me that was amazing . And these trains were faster that I expected . I have been in the Hyderabad mtro already before but compared to Hyderabad metro this metro was far more efficient .
.
And the infrastructure for this metro was amazing . You have several kilometres of underground line which I only have seen in Kolkata that too when I was kid.
.
Well this metro system is by far the best and efficient transport system I have seen and experienced in india . And hope all the metropolitan cities of india will develop similar effective system soon.
