Yesterday I saw this train on SBC PF No.3,there was no Extra SL Coach added,talked to the Pantry Staff,they said Vijayawada used to attach the EX1 sometimes.But based on the coach composition as mentioned in this website,I had booked a W/L 41 ticket yesterday for todays journey,as I thought extra Sleeper would clear some rush.But till now the PNR has progressed only upto W/L 19,with 3 hrs remaining for chart preparation.If extra coach not added,it would not confirm.
