Indian Railways — hijras harrassing the public

Hello sir
I am a frequent traveller. I travel to vijayawada to machilipatnam by train twice or thrice in a week for business purposes. Everytime i board the train, a group of hijras come and demand for money. If not given any money to them, they use a very bad language and even get ready to manhandle. I give them some money everytime to avoid. No one taking action against them. Even passengers also doesn't have dare to talk with them because of their abusive activities. It's very embarrassing to everyone but no one trying to involve. Just imagine if you have to face such type of situation. Pls sir kindly take action on this. Previously many complaints have been submitted. But don't know still why this is happening.
