work is remaining.
Wadshinge to Boroti - Line doubled.
Boroti to Dhudhani - 90 % tracks laid, new platforms constructed at Boroti & Dhudhani. Currently TSR given on this section to complete bridge over Seena river. Due TSR section clearance time increased by 15 mins.
Dhudhani to Kulali - 75% tracks laid and remaining work is in progress. Platform at Kulali is also constructed.
Kulali to Sawalagi - Leveling is progress, only few tracks laid. Construction of new platforms are in progress.
Sawalagi to Gulbarga - 97% work is completed along with construction of new platforms, installations of signals, interlocking work. Only part remaining was 200 m patch at Gulbarga due to ROB.
Now ROB at Jewargi Road is dismantled for track part only and leveling also done. Expected to complete this work within a month.
So hopefully, Gulbarga - Sawalagi, Dudhani - Boroti & Wadshinge - Bhalawani section should be commissioned asap.
Some of the stations like Kem, Bablad are partially closed for crossing trains are detained at nearest stations for 30-45 mins.
As seeing speed of work by RVNL, Jeur - Bhigwan section will take another 5 years as large bridges need to construct between each stations due to Ujani Dam backwater and Bhima River.

interlocking work is yet to be done, but all necessary tracks are laid.
So after doubling, line passing from PF 2 of KWV will be treated as UP Main line.
At present this line goes towards PVR/MRJ, therefore new track laid from KWV LC to KWV Pune end outer at extreme left side.
So this new line will goes towards PVR/MRJ after interlocking and existing PVR/MRJ line will be connected to new line towards Dhavlas from KWV outer. Here also new signaling system is installed and ready for testing.
(At present, construction of new platform beside PF 1 for 24 coaches trains will not be happening, so they will use PF 3 & 4 as usual).
Dhavlas - Construction of new platform is 80% completed. Tracks already laid in entire stretch.
Only interlocking work is remaining.
Kem - Bridge work at Kem outer is completed and PF 1 is closed for constructing new up main line adjucent to it.
Bhalawani - Here also platform work is 80% completed. Entire stretch from Wadshinge is ready for CRS after interlocking work.
After Bhalawani I haven't seen much progress, only leveling work is going on.
