CNB Shatabdi has concurrent schedule with Rajdhanis & in lean winter period, traveler can easily switch!! Been NCR Train, CNB Shatabdi got single Rake whose delay cant be recovered by switching Rake (LJN Shatabdi can switch Rake at NDLS) & foremost, LJN Shatabdi can cover all stations which are catered by CNB Shatabdi but CNB Shatabdi cant do the same!!
