Ok.
Solapur - Gadag was a meter guage line which is now converted to broadguage.
In guage conversion Solapur - Hotagi line of Solapur - Bijapur meter guage was merged with mainline going towards South from Solapur and made Hotagi as a Junction instead of Solapur.
This guage conversion was completed in three steps.
1....
more... Solapur-Bijapur
2. Bijapur-Bagalkot
3. Bagalkot-Gadag
After Bijapur-Bagalkot guage conversion, Basava was extended upto Bagalkot and one intercity was started between Solapur and Bagalkot. This intercity was later extended upto Gadag after Bagalkot-Gadag guage conversion and now a days this is running upto Hubali.
