While travelling from Kurduwadi jn to Pandharpur, or the return journey, don't take for private jeeps and cabs,specially during evening and night time. They will say different price before boarding, but in between the journey they will pressurize you for more fare. And if you object, then they will call their friends (fellow cab drivers) to come at destination to fight off with you.
Always opt for MSRTC bus which cater frequently from/to pandharpur and are safest.
