some demands are totally unwanted like Kollam Rameswaram, if such train is needed, it can go via NCJ, y should it come all way to PGTN and go down.
My suggestion will be
1. Reintroduce old train.
2. Byndoor(bhatkal)-Rameswaram with link from Guv.
3....
more... Palani/MDU - Chennai via PGT, which can be rerouted via PTJ, once POY-PTJ is completed
