I travel Chennai duronto express recently from H. nizamuddin to chennai. the train speed and food what they serve for break fast is good. actually train has no stops. but it stop frequently. and berth cushion is verybad . I got back pain after sleeping. the lunch and dinner were so bad . you cant eat them. dal was not boiled rice half boil. the gravy item was very salty. curd full of water. the tea and coffee were so bad . even you cant sip . toilets were not clean. the flush is not working. water is not coming from taps. dirty smell comes from restroom. attender behavior was very rude . please try to avoid this train. only thing you can find is it reaches destination on time.
