Sir,
I dont mean any offend!!
Anyway, personal security is very much on passenger's own will,
1. Mostly, the train's chain is pulled to stop, @ any pre-fix place to rob & passenger's only are instrumental in acting against any such alarming chain pulling scenario!!
2....
more... Never the train's been attacked or chain is pulled to harass female, but its the very own fellow passenger who behave with that negative approach towards female, sometimes!! Resist & report them!!
3. We @ home safeguard our interest & have to do such, even while traveling. Lock the belongings in seat chain, be cautious near big junctions or unscheduled stops & frankly, dont hesitate in asking ticket less or problematic fellow to either shift coach or report them to authority (TTE/RPF)
4. Some areas are prone for decoit incidences, kindly shut the window in night & keep the door well-closed.
If we are cautious, i dont think IR Traveling is such an embarrassing incident!!
