Don't think trains going to Chennai or south to KL would be shifted or required to be shifted. They are old trains and lot of local travelers too use for commute to areas around SBC station area South West ares like Vijayanagar or MYs road and all old residential areas of Bangalore. If trains like brindavan,lalbagh ,mail, Karnataka, Kanyakumari exp are shifted then it would be the bad decision from SWR in traveler convenience point of view. I feel a train in morning and evening to and from Bangalore should be extended to SVMT if sufficient then around time is available, SBC Mangalore triweekly special via MyS.
