An armed force of the Union under the Ministry of Railways, mandated to protect railway property, passenger areas, and passengers, and to ensure the security of rail travel.
It is a commonly confused force in internal-security and institutions questions; knowing it sits under the Ministry of Railways and is distinct from the CAPFs is a useful discriminator.
The RPF (Railways) protects railway property and passenger security; the Government Railway Police (a State force) handles crime in trains and stations. The RPF is not one of the five MHA CAPFs.
Armed force under the Ministry of Railways (RPF Act, 1957) protecting railway property and passengers; distinct from the State Government Railway Police.
