That I totally agree with you as how slow the IR projects are, it cuz of red tapism, or we may call it babu giri, files going here n there for sanctions etc. it's not easy as a lot of money is involved. IR Should make a system where it decided on projects and hire a private firm to execute it, that's what happens in Germany , the Deutsche Bahn ( Their national rail company) designs and decides the routes to be electrified and give to Siemens , which is solely responsible for DB's electrification projects.
