I have travelled on 12 th of July 2014 in Sampark Kranti express (train no. 12649) from Bangalore to New Delhi in Coach B3, seat no 25 & 27 , PNR 4********7 which is a AC Sleeper coach. I found hundreds of cockroaches and bed bugs, throughout the compartment. I hope it is Indian railways duty to clear all the insects in the compartment. May i request you to kindly do the needful to keep the all indian railways compartments neat and clean. Provide the passengers a comfortable journey.
