Except Rajdhani(average cleaning), I haven't seen any proper maintenance in ECoR trains since long. Let that be Puru, Kalinga or Howrah Superfast. Nandan Kanan/Neelachal ki halat sabko pata hainЁЯШВ. Still didn't expect this condition in a premium like Shatabdi when PURI CDO has no resource deficit. Cleaning order may be set as ER or ECR then SER then ECoR.
