Guntakal YDM4 6446 heading Guntakal - Pakala Venkatadri Express. BG version of Venkatadri Express runs between Kacheguda - Chittoor. I was on my way to SBC by KCG-SBC special and after hearing announcement for arrival of this train I had to run from Pf#1 to Pf#5 to catch a glimpse of this punny beast. Dharmavaram, 2005 08 21.
