SR operates very few expresses within Tamil Nadu !!!!! There are so many from CBE,MDU, Tiruchi dedicated to MAS.
But how many do u find in Karnataka, BGM, DWR, UBL all depend on just one daily night train to SBC- Rani Chennamma. Similarly Vijayapura, Bagalkote have just GolGumbaz. And Koppal, Hosapete, Ballari have to depend on only Hampi. There is not a single daily express train from Chitradurga to its own state capital.
