But, then why its unnecessarily halted to wait before Mahangri departs from Ald for about 20-30 mins.. In that time SK can easily move forward and can easily maintain the gap all the way upto Mgs and it will not at all disturb Mahanagri.. Even the overtake can happen at Bdl too as it will have to halt again at Mzp and will hardly accelerate.. And talking of Mahanagri being not overtaken, then it will not be able to overtake 13202 also, which will create an extra wait of about 20-30 mins at Mgs outer.. Even it has to reach before 1030 to start its return journey ontime..
