My dear friend, the skybus as you say may be more cost effective initially but has a lot of problems if used in the long run, namely: it has low speed at turns as there is a wheel lifting and even derailments, the track has to be stronger and so does the supestructure and the bus body = increased cost.besides this there is the issue of location and management of the fare collection systems and the security besides the problem of managing 25000 - 60000 commuters passing through the station every hour. can it meet that. the indeginious skybus is still in a testing phase and the MD of delhi metro is one of the brains behind its design by konkan railway, do you not think that he would have proposed it himself if it had been feasible.
