Passenger will be able to lodge any complaint as Indian railways is planning to launch a mobile app soon through which anybody can register "Zero FIR" complaint while on board a train.According to the plan, the FIR will be filed immediately registered and the Railway Protection force will take quick action based on the complaint. "The passenger now need not wait for the next station to lodge a complaint. They will be able to complain through the mobile app and the RPF will reach to help them. The complain will be treated as 'Zero FIR' and investigation will begin immidiately," RPF DG Arun Kumar told PTI.A pilot project through a mobile application is already running in Madhya Pradesh, which is likely to be replicated across the country soon.You will be able to file Zero FIR complaints on the app related to harassment, theft and crime against women. The app will connect to RPF, Government Railway Police (GRP) as well as Ticket Examiner (TTE) and train conductor. The app will also have a panic button for women in distress. You will also have an option to raise complaint offline.Zero-FIR are First Information Report that can be filed in any police station, irrespective of place of incident/jurisdiction. These FIR are later transferred to the appropriate police station for further investigation.Currently, if you want to report any complaint, you have to fill a complaint form provided by the ticket examiner and that form is later submitted to RPF or the GRP at the upcoming station.The complaint gets automatically transferred into an FIR, but the old system often lead to delays and passengers don't get immediate relief.
