Railway Electrification from Daund to Wadi via Solapur- The southern arm of the Golden quadrilateral is still incomplete. The track between Daund and Wadi via Gulbarga & Solapur is partly single track and also still not electrified.The trains from Mumbai/Pune to Hyderabad/Bengaluru/Chennai are all passing through this line which is a bottleneck. fail to understand why Central Railway and RVNL are progressing so slowly on this sector. There is no major ghat section nor any major river bridge.Deliberately slow.
