If a Jan Shatabdi is present then why are you preparing a Shatabdi?! How fast connectivity do you require! See the attached pic which tells us about the availability of the existing Jan Shatabdi (12054). See, most of the 2S are vacant and a thin waiting list at the CC coaches. And you are preparing a full AC Shatabdi. Do I need to say anything else that it will be a super-flop train?
