Mgs-Patna best time is 2 h 55 mins for Archana, other all trains take more than 3 hrs, but with Rajdhani clearance its been done in 2 h 30 mins mostly by Rajdhanis and even sometimes Sampoorna Kranti.. TT revision is required in this section... and a little slack can be provided in Ald-Mgs for delays of all trains
