Indian Railways — Worst condition of Shramjeevi express..

Hi, right now I m in Shramjeevi express, it's such a bad experience to be here in the 3rd AC compartment of the train, it's B3 n the last coach after the guard of the train, u can understand the condition.. no water is available in the train, from noon no vendor came for tea or coffee as it is the last coach n it is not linked to other coaches, the worst thing is that water supply is too bad n the water which is there is so dirty that it can cause infection. I don't understand why Indian railways are not providing can good services when they r taking a good amount for it. Today how much difficulty we faced we only knew as there was no platform for us to reach the coach it was outside he limit of the platform, plz tell me that I m having an injury in my leg now a n I have a baby also was it possible for us to run with the luggage, to reach the coach? N what next, no water in summer, how to get water when the coach is not reaching on any station platform n no vendor is coming. I have experienced these type of worst services before also. Indian railways needs improvement.
