Its a useless extention upto satara. Instead this train can go via pune-satara-miraj to pandharpur. No loco reversal. This will give good connectivity to satara to miraj and upto pandharpur from mumbai as other trains reach between satara and miraj at very odd hours. The train can depart from DR an hour before and reach pandharpur by 1130. Return it can start at 730pm. It can be routed via panvel if there is congestion on main line.
The pune-kurduwadi-pandharpur connection is available by other trains
