Atleast now, SWR should think of linking JTJ line to YPR line at SBC, by modifying back entrance area to bring JTJ line to PF 8+10 and/ or YPR line to PF 1 to 7.
This will give lot of flexibility to operate train via SBC.
Also, a link near Lottegollahalli for linking Hosur line to Yelahanka line. This will provide lot of flexibility to operate more trains from HOSUR side to YNK Doddaballapur, Airport.
