Took this train from Vijayawada to Secunderabad and decided will never again. It’s my mistake too that I didn’t notice that it’s not superfast train. Stops at every station and after joining Kazipet line, kept in loop for 5 superfast trains to cross. It took 7 ½ hours to reach Secunderabad and distance is 300 kms.
2nd AC compartment is clean and pantry is good. Go for it as last alternative and seems seats easily available till Secunderabad.
