I think Survey has completed for doubling of this route but doubling not sanctioned yet.
This route partially passes through hilly area & has tunnels. As railway was feeling this route risky; initially, for many years, it was open to goods train only. Later on permitted for passenger's trains.
Demand of local people is correct.

Actually,...
more... there is need of shuttle service between LNVL-PNVL. Pune locals ply upto LNL & Mumbai locals ply from KJT-PNVL but there is gap of local service betwn LNL-KJT-PNVL due to Ghat section. So, such shuttle service will be very popular.
