Karnataka is the only state which has 5 different zones operating, but only one zone having any division/ zone HQ. When SCoR is created, they will also 'serve' Karnataka, making it 6th zone in the state!!.
SWR is the main player. But surrounded by SR for Mangalore, SCR for NE Karnataka areas, KR for coastal areas and CR for Kalaburagi. Only SWR has 3 divisions in Karnataka. All other zones just operate with their preferences elsewhere. None of the 4 neighbouring states zones are interested in providing anything good for public.
For...
more... getting a Mangalore to Bidar train, you have to approach SR Palakkad, KR at Navi Mumbai, SCR Guntakal/ secunderabad and CR Solapur.
Until unification moves are done, Karnataka will suffer in intra state train connectivity.
