Indian Railways — late arrival of train

The train no: 17643, circar express, between chennai egmore & kakinada. This train is arriving late by 2 to 3 hrs to kakinada every day. & all the a/c coaches are very badly maintained & bed bugs & cockroaches every where. Due to late arrival every all the further plans for the passenger are delayed. As there is no pantry car facility, small childrens are very much affected, as they are not getting morning breakfast & food sold out side vendors are not hygine. This express??? Train is running like passenger train, stopping at all small stations & stand a side, leaving path to other express trains. Railway management must look into this issue immediately, as this is the only direct train connectivity between chennai & kakinada.
