If you ask me about SR I will say a big zero. It no longer has any desire to operate new trains both inside and outside the state, probably the worst zone in IR. MAS has also became the extension capital of india, with already losing few trains in the past and still demand soaring for extension of some trains beyond it to south TN, kerala or bangalore. When bangalore or hyderabad can have so many dedicated trains I dont know why extension of train always demanded only from MAS. Is this not ridiculous? People wanting more trains to rameshwaram, kanniyakumari, nagercoil, trivandrum, bangalore, etc should demand separate trains rather than asking MAS to part with !
