04452 is RT!! 04451 delayed in CNB-ETW as as like other trains from CNB which DEP after Rewa Exp @ 23:30 like SS, Vaishali, Poorva, Prayagrah, PRYJ HS, RJPB Raj, SK, CNB Shatabdi, HWH Raj, DBRG Raj, SDAH Raj, BBS Raj,etc...all delayed & recovered later on to some extent. Magadh Slack in TDL-ALJN may make it recover provided it dont loose horrible time for CNB Shatabdi/SDAH & BBS Raj OT while already OT by DBRG Raj!! Kindly check before criticize!!
PS: CNB Shatabdi OT by HWH Raj & it will be interesting to see if it avoids OT by SDAH/BBS Raj @ ALJN!!
