No, way there are many constraints in it.. For that it should be given the priority of a duranto to reach on time, otherwise it will be overtaken by Rajdhanis on daily basis.. As observed by me, if it departs Kanpur before 0230 h. Mostly it reaches on time, and as soon as it departs after 3 am from Kanpur, it doesn't gets the same clearance and get overtaken by Rajdhanis around Aligarh.. Whereas even in that 1 hour of so it maintains the gap of around 120-140 kms, yet it gets overtaken within next 200 kms. Such is the treatment.. Instead it should start at 2200 hrs from Rjpb and reach at 1150 hrs and Ndls, just behind Sdah Duranto..
Or...
more... Patna Rajdhani should be run like old days 2200 hrs from Patna and reach at 1015 hrs..
And SK should be rescheduled to reach at 0800 hrs..
