Travelled on 23rd by Cocanada Express 2AC it arrived late by 40 mins at Bhimavaram Town and Secunderabad at 7.30pm. Coaches are creeky and old. Fellow passenger with side lower berth requested TT to change berth as its very uneven and the toilet door was unlockable from outside. Narsapur express 2AC coach is well maintained and is always the first choice for passengers from Bhimavaram as it runs almost on time.
