Southern Railway — Regarding Transgender in Circar express 17643 train

I was travelling in Circar express train no 17643, when the train arrived Chennai Egmore the transgender people entered into the train and asked for money I have given some money they demanded high amount and raised their sarees and shown their private parts and talked in rude language and beaten me and stolen my money from the pocket, this is not the first time it happened so many times while I was travelling in this train especially happening in Chennai Egmore. Kindly requested to authorities to punish them and provide security to the passenger it is the responsibility of Indian railways.
