Magadh is trolled every day in NCR, and can be speedup easily.
Recently traveled in it from DDU to MZP and later took Triveni Exp from MZP. Magadh departed on time from DDU and was halted at jhingura for 45 minutes and both sampoorn kranti and Patna rajdhani express overtook it and reached 20 min late mirzapur.

The ideal controlling would have been Magadh at MZP and till sampoorn kranti can be kept behind. Later when Magadh departed from MZP and arrive at BDL then sampoorn kranti can be kept on loop at MZP. During the halt of sampoorn kranti at MZP and magadh halt at BDL, Patna NDLS Rajdhani express should overtake both of them and then sampoorn kranti can overtake magadh at BDL.
I strongly in non favour of stopping any express or superfast trains in station that have no facilities and are deserted as it can cause theft.
