I still say this is nothing more than an excuse!! Mahananda once overtook some HS in between CNB-PRYJ, coz HS got broken spine..but Mahananda got 1 or 2 stops past OT before PRYJ (plus immense slack)!! What happened was: HS awaited for OT, lost time waiting & then with 60 MPS was trolled by 110 MPS stoppage train which pushed HS to be looped for PNBE bound trains in PCOI-DDU (the average time given to most train in PRYJ-DDU can be covered with 50 MPS)!!
Outcome: Delay which should be of 1 hour turn out to be 4 hours!!
