It takes time and sure karnataka gets good rail infra same like Andhra TN Kerala Maharashtra. Presently works going on for doubling of all the routes in Karnataka and also RE is sanctioned and New lines also emerging slowly. On other side karnataka have more dense forest area which is barrier for rail lines due to environmental issues which can't be taken as backward or failure in rail infra as it's by nature we can't do anything on that but whatever area where rail lines can be feasible those all lines get done in future. AP TN Kerala all have good rail infra from begining it's not new development but karnataka except Bengaluru Mysuru now it's improving rail infra in other parts of state too. For good and better things obviously it takes time which is what we ppl of karnataka waiting with patience.. SWR sure will...
more... emerge one of the best zones of IR in future.. It's just begining of its development now..
