As I m from that Region,I m giving my views.
1.Extend the train to Kollam/Kochuveli
2.5 minutes stoppage at Tenkasi Junction is Enough.
3.Unwated stoppage of 5 minutes is given at Rajapalayam,Dindugal and Budalur.
4.There...
more... is no station called cholapuram between SNKL and RJPM.It was there before years in MG period and was abandoned later.
5.Remove stops at sholavandan,Ayyalur,Manaparai,Tiruverumbur and Budalur,Saliyamangalam,Ammapet,Koradacheri(All these are purely passnger train and MEMU halts) Its unneccessary for an express.
6.5 minutes stops at nidamangalam is unwanted 2 minutes stoppage is enough.
Here i have given the practical facts about this Route.
Thanks.
