Instead of depending on CR, why not a SWR train from Mysore to Pune via Hubli Dharwad Belgaum? Starting from Mysore by around 7 PM reach Belgaum by 6 AM and reach Pune by 1 PM. Can return by 3 PM from Pune reach Belgaum by 10 PM and reach Mysore by 9 AM. This can act as a ONT from Mysore to Belgaum and ICE from Belgaum to Pune. After Belgaum, keep 1 3A coach as CC and few sleeper coaches as reserved sitting. Will be a super hit.
