This current move is to get WADI KLBG out of SUR and merge to SC division. As long as KLBG SUR is with CR SUR, SWR cannot get access to KLBG area.
Another advantage would be seamless single interchange at DMM will ensure a good train from Bangalore to Bidar via KLBG. Now to a kid CR, trains are run via Vikarabad.
If Wadi Kalaburagi comes under SCR, you can have many trains originating from Bidar to south Karnataka and even Tamilnadu via Kalaburagi -- say for example Bidar to...
more... Mysore via KLBG GTL HAS, Bidar to Tirupati/ Chennai via KLBG GTL, Bidar to Trichy/ Ernakulam/ Madurai/ CAPE via KLBG GTL KJM SA etc.
North south traffic can also get trains via Wadi KLBG Khanapur, Latur, Nanded.
