Did I ever say SHAR is in TN? No, I did not. I said Gummidipoondi is a suburb of Chennai, and SHAR "almost a suburb" which did not obviously mean it is. Of course, Sullurpetta is the nearest railhead, and I vouch for it, but for all practical purposes, it is Chennai. FYKI, Pulicat Lake is shared by both states. And, if I can add up one more thing to Siva-Ji's post, the Sree City is going to house the Alstom factory that is going to supply Chennai Metro's rolling stock.
