Overall bad only, in before last train beyond VPT was 12631 @ 21.15. Then changed to 20:50; now again changed to 20:10. 4 trains continuously towards VPT, SRT, MEJ, TN/TEN starting from 17:30 Cape; 19:15 Pearlcity; 19:35 Anantapuri; 20:10 Nellai. Thereafter no train. If Silambu extended to SCT; then again 2 train continuously to SCT @ 20:20 and 20:50. What mistake south peoples made?!!!!!!!
