Superfast made a supercrawler by NCR...Covered 155 kms in almost 8 hrs.. If track congestion is an issue then how come 12150 Patna Pune departing Patna 3hrs after Sanghamitra managed to reach ALD before Sanghamitra.. I think this train is targeted or what... Best option would be like run this train PNBE-MGS-BSB-ALD and then it's normal route this will neither take anything from Allahabad passengers and in addition Varanasi will be benefited and definitely improve its punctuality like in the case of Bagmati though it doesn't touches Varanasi and bypasses at Cheoki
