I am just wondering where was the idea when the metro system was conceptualised...In India...why do people bring up thousand issue when they know that time has already past when they could be put to use or someone whould have given them a thought.....Well....I don't think we have given metro rail enough time to show what it's real potential is....even new small factories set up take 3-5 years and Man, this is METRO rail.......you will know Some of points mentioned in the article are wrong itself if some have been to London or NY
