Ever since the starting of this train service from its inaugural run to till date, now almost 15 years were passed.why the frequency of this train is not increased ?Still it is running as weekly Express only.Where as if the same train was running between Kerala & Rajkot means, by this time, it would have been made as daily by increasing the frequency frequently in between at regular pace into biweekly, tri weekly & then to daily etc.It shows there must be some group behind that to prevent increasing the frequency of not only this train, but also all other trains originating from Tamil Nadu area.
