Traveled from New Delhi to Agra. The best possible option after Shatabdi and Gatimaan. Best for railfanning. Maintained its punctuality very well, arrived at Agra just 2 minutes late. The P-7 from GZB did a good job in maintaining the speed all around. Traveled in the CC coaches hence could not tell about the 2S. The CC Coaches are bit dirty. No cleanliness nothing. Toilets stinking badly. Even after complaining to the TTE, no action was taken by the authorities. Apart than a good option.
