Since all the construction for Commonwealth Games was undertaken, some of it finished on time and some not, some phrases are thrown around in Delhi press, indiscriminately, in my opinion.

I was in Delhi, for nearly two months. I can see that it's much easier to negotiate now, than it was before the Metro, although, metro has it's own problems, mostly due to the people who use it.

The airport is nicer too. But in my opinion, Delhi is not a world class opinion even with the swanky airport with all its glittery pictures and the Metro, which is better that some Metros I have come across, the one in Istanbul and the one in Washington, D.C., to name a couple.
The fast and efficient metro enables you to travel long distances in Delhi rather quickly. The longest I had wait for a train was 8 minutes, and that was late at night. During the day, the trains were very frequent. If you missed on another would be there in as little as a minute.

Once different modes of public transport are properly linked, Delhi would be a little closer to being a world class city, but far from it. For example, there is no way to get to the निज़ामुद्दीन -Nizamuddin- Train Station (NZMD), or the nearby ISBT at सराय क़ाले ख़ान, - Sarai Kale Khan-of Delhi using the Metro and it's difficult to get there by buses too, from some parts of Delhi. Both, New Delhi (NDLS) as as well as NZMD have entrance on either side of the tracks, but you have to use steps to get to the building on each side, and use a bridge with stairs to go from one side to the other. The same situation At NDLS, which also has a metro stop, I could not find a way to get to the railway station from the metro station without coming to the surface, walking up or down the stairs, and walking through lanes of traffic or parking for taxis. I am told one can go from the Metro Station to the Irport Express station under ground.
The pushing and shoving has simply moved from buses to Metro, when passing through the security check point, when swiping your token or the smart card, or depositing your token, as well as when getting on or getting off a train.
As you are putting your bag on the security belt, however small it might be, one or more people would always reach from behind and put their stuff ahead of yours on the belt.
People negotiate their way through crowded platforms/trains by putting their hands on you (your back) as if they were swimming. Even when they are lined up before the arrival of the train, all order disappears once the train arrives as if a big cat (lion or a tiger) had been sensed by gazelles.

Some people act is if they have never seen, which is probably true, an elevator. They run to one, as soon as they have pushed around the old, disabled or those with luggage, to crowd around the elevator. Once, when I managed to get on one with a small carry on, the elevator would not budge as it was overloaded. So I looked around and picked out three people who were not old, disabled, pregnant or carried luggage. They were probably in their early twenties. One pointed to his laptop shoulder bag claiming it to be his luggage.
On another occasion, I grabbed one guy by his jacket as he pushed his way around me to get on the train while some of walked towards the door. The guy retorted "He is breaking the line too. Why don't you stop him".
With behaviour like this, Delhi will never be a world class city. People drive as if they are walking. If some one is in your path, go around him. Their only concern is to get where they are going. They will break every rule of civilised driving. Once, I was nudged by a car coming from behind. I was walking on the road, as side walk was occupied by vendors and illegally parked vehicles. I wasn't hurt terribly, but was taken aback. I was about to say something like "Look where you are going man!" or something like that, but was preempted with "Can't you see where you are going?" No one ever wants to admit of the possibility that they actually might be at fault.

World class city? No sir. Indian pandemonium.
