It was under Muniyappa, the RSA trains were granted to Mysore and Shivamogga. I guess you havent travelled recently in the stretch b/n TK-ASK and JRU-UBL. Suresh Prabhu sanctioned additional funds and the same is avl in pink book. Kharge was equally good in getting trains to GR and BIDR, UBL-SC etc. But that wont negate the contributions of Muniyappa and BSY.
