Initially SWR showed reluctance to throw the line open to public. When protests reached peak, just introduced one train between MAQ and SBC. Cunning SR extended it to Kannur when coastal karnataka people wanted one train to their towns!
The constrains have not appeared from moon. They were there earlier also. These should have been taken care of while designing/ converting MG to BG. Else, they should have left the MG as it is between Sakleshjpur to Mangalore Jn. After spending crores of rupees and after a decade, the reasons seem silly to cover up the mistakes/ errors. Assuming that 2 stns have problem of siding etc., do not provide stops at these 2 stns and let the train run at slow...
more... speed in those problematic stretch.
