"South" Passenger? The Chennai-gang named this train thus when we saw it standing at Gudur Jn. Actually AP passenger might be better as lots of major SCR stations are covered (AP-ites pls translate). Note passenger train numbers. The board translates as follows: VijayawadaOngoleVijayawadaBitraguntaTirupati
