please go and have a look at the availability in no 1 political shatabdi of all time chandigarh delhi shatabdi and then talk about pune sec shatabdi...just because delhi is the capital does not mean every one wants to goto delhi, most of the premier trains run from there and most of them are not having good occupancy even though they have been running from years and years...go and check availability in them and come back to this only shatabdi from pune and secunderabad
