ЁЯФ╣Let this train remain as SF. No problem
ЁЯФ╣IMO don't take any train from North Karnataka to Bengaluru after Mysuru. People might not prefer it till Bengaluru because route will become longer. You can do reverse i.e., take a train to Mysuru after Bengaluru. It will be successful
ЁЯФ╣You can take any train to Chamarajanagara after Mysuru. People will use it because Nanjangudu and Chamarajanagara doesn't have proper train connectivity with most of the places either within Karnataka or outside Karnataka
