Police The Government Railway Police (GRP) is the police force that is responsible for policing on the railway stations and trains of Indian Railways. Its duties correspond to those of the District Police in the areas under their jurisdiction, but only on railway property. While Railway Protection Force (RPF) comes under Ministry of Railways, Government of India, GRP comes under the respective state police or UT police. Police Commissionerates Some major metropolitan cities use the police commissionerate system (like Delhi, Mumbai, Chennai, Kolkata, Bengaluru, Hyderabad, Ahmedabad, Lucknow, Jaipur etc.), headed by a police commissioner. Demand for this system is increasing as it gives police a free hand to act freely and take control of any situation. 68 large cities and suburban areas currently have this system in India. Even in British Raj, the presidency towns of Calcutta, Bombay and Madras had commissionerate system. Reporting to the Police Commissioner (CP) are the Joint Police Commissioner (Joint CPs), Deputy Commissioner of Police (DCPs) and Assistant Commissioner of Police (ACPs). Commissioners of police and their deputies are empowered as executive magistrates to enforce Section 144 of the CrPC and issue arms licenses. Police commissionerates are subordinate to the state police except for the Kolkata Police, which independently reports to the Department of Home of Government of West Bengal. Traffic police Highway police and traffic police in small towns are under the state police; traffic police in cities are under the metropolitan and state police. Traffic police maintain a smooth traffic flow and stop offenders. Highway police secure the highways and catch speeders. Accidents, registrations, and vehicle data are checked by traffic police. State Armed Police Forces The State Armed Police Forces provide a state with policing in particularly violent or serious situations, such as combating banditry and Naxalites. Like the Central Armed Police Forces, they are known unofficially as paramilitary forces. Each state police force maintains an armed force, with names such as Provincial Armed Constabulary (PAC) and Special Armed Police, which is responsible for emergencies and crowd control. They are generally activated on orders from a deputy inspector general or higher-level authorities. List of the State Armed Police Forces are hereinbelow.
