this train departs from guntakal junction @ 0.5. and arrives yeshwantpur junction @ 9.45. between these 2 station, it halts only @ dharmavaram junction and hindupur. but, it takes too much time from guntakal to yeshwantpur. (9 HR and 40 M). is there any technical reason? because, no other train take such a long time to cover same distance.
