Indian Railway — Bag snatched while sitting in train

My Mother and her 2 friends with my younger sister were travelling by RXL-HWH express, in night while talking, the train slowed down near simariya station and a 15-16 year old boy suddenly came snatched the bag and went, They were left without any Cash, mobiles etc. and my mother was hurt, That too in an unknown place, we had to rush to take her from the station. Surprisingly there was no TC and Police man in the bogie .Also when trying to stop the train .None of the chains worked, This is an atrocious situation. I don't know i can have faith in Indian government anymore.
