Regarding KCG Dhone route another story
When Gadag was under UBL division of SCR their was continuous demand for GC from Meter Guage to Broad Guage of Gadag Solapur MG line but Corrupted politicians for Bus lobby was always trying to delay the project and it dragged nearly I think 13 years for GC of 300km and amount was sanctioned but no one was utilising it for GC due to buss lobby politicians pressure and that time some of the amount transfered to Mahbubnagar GC works as both sections were under SCR so that time KCG Dhone /GTL became BG line and This Gadag Solapur line in phases from 1994/1995 upto 2008 it took to be complete BG line...
more... from Gadag to Solapur. Instead of that much time the line quality of works was third class no proper alignment steep curves no line banking in curves and signaling works were also poor which GM itself told when ppl demand him run trains at faster pace then he replied line not upto that standards to run trains faster and need improvements in signaling also.. now recently some stretches made speeds of 60 to 80km and some of 90mps but trains don't cross 90 mps in whole stretch except Between Lakhmapur Badami and some section between Bijapur and Solapur.. These all things I got from inside job of railways employees as I know most of railway employees of old age I use to discuss with them of past railway system in this area so that time I come to know all these things which I shared to you.. I don't have any paper clips or websites to refer this with them and also I don't think any railway zone or division will publish or let to publish such inside matter in any publications too..
