I have read of other lines like Bidar - Nanded and Shimoga - Shikaripur - Haveri / Ranebennur and Gadag - Haveri. If these are implemented, then we would have a trunk route connecting several places in Central and North Karnataka to Central and North India.
If Shimoga - Shikaripur - Haveri - Gadag rail route is laid, Shimoga too would have a trunk line to Nagpur, besides good links to places like Hubli, Gadag, Bagalkot and Bijapur. Haveri - Hubli and Gadag would form a triangle thereby paving way for industrial development and creation of jobs. Also, despite being the HQ of SWR, Hubli does not have proper trains to many places; this would change once IR takes up projects of...
more... this sort.
Leaders of North and Central Karnataka should impress upon the railway minister to sanction this project as it would do a lot good for Hyderabad - Karnataka and Vidarbha regions in both the states. Maharashtra's leaders would also support the move as Vidarbha's links with Bangalore and the rest of South India would improve thereby facilitating healthy socio-economic progress of the region.
