Indian Railways — theft of mobile phones in running train

I have lost my 2 mobiles from grand trunk express 12615 in between faridabad and hazrat nizamuddin station today morning. There was no grp police staff nor train superintendent or tte in the whole sleeper coach. I asked help from tte in ac coach but he denied to help and said contact sleeper coach tte. I have a reservation in s4 coach birth number 62. I need your help so that i will get compensation of my lost mobiles because it is the responsibility of railway to ensure the security of passengers goods. If i didn't get proper help and compensation from indian railway then i may also move towards court for justice.
I already lodge complain to grp and filed fir but didn't get my phone yet so please don't suggest me for that again in comments or closing remarks because i am complaining the second time. If you are still not providing the justified help i will go to ministry and higher authorities. Sleeper coach is for sleeping during the night not for guarding mobile phone which is kept inside a bag. The incident took place between 1:00 am to 4:50 am. I have also clear doubts on my fellow passenger who has seat number 32 in my coach in the same train and he comes to near my birth during night because train has vaccant seats.
