There is no way SBC/YPR can expand any further. So remove those 2 options.What all are remaining?????KGI-Nope ,Whitefield-Nope, KJM-Nope, BYPL is the only option. As far as how much I know, it cant be expanded with many pfs. It has 2 or 3 I guess that's it. Only pit lines/slack lines can be provided for trains. Else dont ask any trains from Bengaluru. Ask from Hassan/Mysore which can run via Bengaluru.This is as per my knowledge,you are free to ask actual people involved in IR as to what is the solution for these.....??
