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

Hey SCR/ScoR fans, I have a small question. How come this train is maintained in 1 hr at COA? The incoming train arrives at 12 pm and the return departs at 13:55 pm how? Do they have any other rake at Kakinada already like Kerala Express at TVC?
