Chennai and Bangalore are the first two routes which have been having high demand from Coimbatore for more than 2 decades. If you say, CBE-SBC ONT wont get demand, either you have no knowledge of the travel scenario in CBE or must own one of the Pvt buses in CBE - BLR route.. :-) And never judge a route's capacity based on a SPL train which was operated on a weekday and that did not reach the public much too. These are routes which need consistent schedules and reliability. Commuters will look forward for daily trains at right timings. Now the CBE-SBC route is dominated by pvt buses.
