Yes Sir a Quadruple Line is much needed. A third line is in Operation from Ennore to Korukkupetai.
I Agree with You Sir. A Shed will be Good at Tada coz it is Having lot of Railway Space and Sullurupeta doesn't and Gummidipundi is already Taken 2 Pf's Out of 4 for Parking Emu's at Night. Now Tada is a International Industrial Area due to Sricity SEZ.
