Actually TN people are only going more to Bangalore than KK people coming to chennai. You yourself has mentioned in past blogs about that TJ need train to SBC. See we in TN have train from chennai to all places. Imagine if we had no uzhavan,mannai,pandian,nellai,pothigai,cheran,yerc aud etc. and have only train like PC , QLN Mail and Boat Mail as in british era. How it will be ? Same is the situation of KK now with having only less trains for them. Still some more needs to be introduced for them. Anyway , the national parties don't care about TN. Save ur energy :)
