Kamayani Express - Late आना है काम तुम्हारा लेकिन मैं फिर भी हूँ तुम्हारा दीवाना - Aman

YPR-SC Garib Rath is one of my favorite and most convenient train for me to travel between Bangalore and Hyderabad. I've travelled more than 20 times in this train till now. But there is one thing I still don't understand about it: Upto GTL, it runs either 10-15min before time or dot on time. After GTL, it always delayed between GTL and LPI. Sometimes by 45min, sometimes 1hr and even 1hr 30min+ sometimes. Once it got 2hrs delayed. It wasn't weather conditions either. Even though this line is doubled and electified fully, many trains in this route are frequenty delayed. Does anyone know the reason?
