I don't think the delay will further increases...if you see the TT then the slack it got at SKZR-BPQ,GDYA-ET(70KM 2h 12m),STA-MGS (all most all the section it has slack till it reaches MGS) and slack at the last leg of journey ...so combining this slack with the priority it gets in SR and SR ..I don't think it will have problem covering its path with the prescribed schedule even thought it started late from source....if there is any other issue like fog n all then we cant do much about that :)
