for tomorrows run nearly 275 seats available from pune to sc after chart preparation ..just for the sake of shatabdi they run it during morning , i think if this can run overnight( although against the concept of shatabdi ) and cover distance in 8 hours then it will run full....it will be faster than buses , cheaper than buses + more comfortable than buses too..IR has to be innovative in order to use the resources properly ...on weekdays every day u can find 100s of seats empty in this train ..
