The train timings shown in arrival departure history are too much wrong. the train timings for departure date 3 - march are as follows
Tenali 23:12 23:32---it came 10 min before and due to single track from tenali had to wait for signal till 11:32
Guntur 00: 20 00:45---waiting for engine change.
Secunderabad 06:00--45 min late in all..
