Actually I was traveling from Eluru to Visakhapatnam. I reached the Eluru railway station at 1 pm. Then the train announcement was made For (22416)Andhra Pradesh AC Express which was the train that I must travel. Then suddenly after 5 mins the train came to Eluru railway station. This train was Secunderabad-Shalimar AC SF Express which appear to be same as AP AC Express, this train came to an unscheduled halt at that station. I didn't read the train board and I got in the train in hurry. Then at Rajahmundry Railway Station I got down for coffee. Then I saw the TB written Visakhapatnam-Secunderabad-Shalimar AC SF Express. Then I climbed the Upper berth and slept for 3 hrs. Luckily the TC didn't came for checking ticket. And at 5 30 pm Visakhapatnam arrived and I got down there
