travelled in this train last night from chennai to bangalore, in s14, the coaches are worst and pathetic, SR lacks in maintainance, Earlier when it ws in SWR, it ws gud,,,,CBC coupling is resulting in sudden jerks during deep sleep,,sometimes it happens to be falling down from the train,,speedcws god, it was hauled by an LALLAGUDA WAP7..reached sbc at 3.50am........gud train with bad maintainance.....
