Indian Railways — train delay and no confirmation

I have been travelling from kerala to chennai with my parents in mangalore express (12686) train had to be reached by 8.30 but it has not reached till 2.00pm still on the way if railway should atleast provide some food and water no facility available they take all the money they required waste.. If there is any issue in train delay there should be should be message so that we can arrange some food as railway authorities so not provide any facility kindly do some action against the same or keep some system to keep people update about the delay so that we could be well prepared 1 or 2hour is also ok but a train reaching at 8.30 am is reaching at 4.30pm is this not an issue are the railway authority sleeping kindly take some feedback
