It's not bus lobby it's Hubli Zonal divison office lobby to compensate Goa link express and Karnataka railfans think it is justifing the name Karnataka SK by covering most dts of KA. Infact KA SK should have been daily with 4 days via Kurnool and 3 days via Raichur SC sharing the same slot in combined route. SWR should have planned an SF from Hubli to compensate or increase frequencies of present SJ SK to daily by running in different routes covering other dts of Karnataka.
