Even in the 21st century its quite impossible in our country for a superfast train to maintain even a mere avg. Of 55 kmph ...Look how pathetic attitude railway board has toward this train..never runs on time..reaches its first halt by a delay of 5-10 minutes then reaches Hajipur with a delay of 15-20 minutes and reached gkp by a delay of 40-50 minutes and in crossing lko and cnb the delay goes upto 3-4 hours in every single run..even today its running late by more than three hours...so railway should either remove the sf tag or should run this train with min. Delay... I don't really understand what are the factors which force a sf to run late by more than 3 hours...
