I doubt whether the last part of the video in which the train Overtaking T.N. is A.P or not. I knew both AP and Rajdhani Overtook TN at Wirur, but the pictures which where taken at KZJ Bypass indicate that the Loco for A.P. was 30326 and the train which overtook TN at Wirur had 30287. If am not wrong in the later part of the video the train has to be SBC Rajdhani.
