I am not talking about linking at Lottegollahalli. I am talking about a inverted C or U in SMVB exit point towards Banasawadi side. There are two lines merging there. One from hosur line bypassing SMVB and another from SMVB. If these are linked, one can have trains from YNK side enter from BYPL side and exit via bypas line. Even one can run Whitefield/ KR Puram side trains to Hosur line.
Just imagine Hosur Heelalige SMVB YNK Airport, Hosur SMVB YNK DMM, Chennai KR Puram SMVB Hosur. No loco reversal required
