AND with a mere avg speed difference of ~ 3 kmph between ALD-ANVT/NDLS and travel time difference of approx 20 minutes compared to 1, 2 and 4 the train mentioned on number 5 is termed as SLACK SF Express whereas the above trains numbered 1,2,3 and 4 are HIGH SPEED trains. 12303 and 12559 have same timings yet 12303 is said to be fast sprinting train whereas 12559 is slack SF. I wonder do these people really see before commenting all utter nonsense coming throughout their mind. And to paraphrase more about these self appointed volunteers of 1,2,3 and 4 numbered trains ,few of the volunteers have not traveled in any of the said trains or have traveled once or twice not more than that.
