Agree after LHBfication, all ICE or Janshatabdi all are same, there are only three typs of coaches now, LHB Chair Car 3X3, LHB AC Chair Car 3x2 and Executive Chair Car AC 2x2. As far as SER is considered there is now no difference between Ispat and BBN JS, the AC of both JS, Ispat and Steel are same as that of RNC Shatabdi, all being LHB. Steel's EC is also same that of Shatabdi EC. Ispat having a 3A is a different story all together.
