Who says South India does not have Gatimaan. It is called Vaigai Express. - Thamizh Maran

Yes good option if they are able to explore that well. It can also give suburban circular connectivity to places between Hosur-WFD, BWT as well . From BAND when one connects to Salem line , they can form something similar we can see at Shoranur ( like a V shape) where a line from the terminal can also join.
