But, you won't find any sort of foul smell inside the Delhi Metro Express Line.
Here, people behave in a civilized manner. They don't do hustle and bustle to get inside the metro. In fact, many of them will ask you to make a move first with a pleasant smile on their face. Even they will help you place your thing properly in the racks inside. This must be learned by each person traveling in metro. Moreover, the Delhi Metro should itself make a move to make the system function properly unlike the Airport Express Line.
