Ohho. So the RTI reply was a bit outdated. I think, the works regarding conversion of 18 and 14 coacher pitlines to 24 coacher has already started. I have seen few works going on there.
I feel parking space (for trains like darling, falcon, Narayanadri etc) near to SC is more of need of the hour than more pitlines. But sadly, there is no sufficient space for that.
