Well when there are two trains, namely MAS TVC SF exp and SF Mail, can't they adopt an alternative stoppage? Say one stops in Chengannur the other can skip it and stop in Changanassery. We can save considerable amount of time like this. Does every train need to stop for every 10 kms? There is a high need of an MPS increase in Kerala especially the south. I know the route has a lot of curves and 80 can be the max speed but I do believe significant amount of speedup can be done provided frequent halts are removed. I strongly believe ERN TVC can be done with 3.5 hours if this frequent halts are removed and a little MPS upgrades are done.
