Example where too much of slack is ultimately detrimentral to the train in question.
This train arrived 1 hrs before time at Dhanbad and was detained for 1 hrs and 20 mins well past it's scheduled departure. It was overtaken by an almost on time running pair of 13152 @Dhn and 12988@ASN.
Yet it is very likely to make up it's lost time before reaching BWN
please wait...Translate to HindiJab zyada slack ho train mein, tab woh nuksaan pahuncha sakti hai train ko. Yeh train Dhanbad pe 1 ghante pehle pahunchi aur wahan se 1 ghante 20 minute tak roki gayi apne scheduled departure time ke after. Lagbhag time par chalte hue 13152 wale pair ke saath Dhanbad ke aur 12988 ke saath ASN ke usko peeche chhod gaya. Fir bhi bahut possibility hai ki yeh apna miss kiya hua time cover kar legi BWN tak pahuchne se pehle.
