Metro Security
Security is main and important issue at all over metro stations. Security on the Metro is handled by the Central Industrial Security Force, who has been guarding the system ever since they took over from the Delhi Police in 2007. Closed-circuit cameras are used to monitor trains and stations, and feed from these is monitored by both the Security force and Delhi Metro authorities at their respective control rooms. Over 3500 security personnel have been deployed to deal with law and order issues in the system, in addition to metal detectors, X-ray baggage inspection systems, and dog squads which are used to secure the system. About 5,200 CCTV cameras have been installed, which cover every nook and corner of each Metro station. Each of the underground stations has about 45 to 50 cameras installed while the elevated stations have about 16 to 20 cameras each. The monitoring of these cameras is done by the Security Force, which is in charge of security of the Metro, as well as the Delhi Metro Rail Corporation. Intercoms are provided in each train car for emergency communication between the passengers and the train operator. Periodic security drills are carried out at stations and on trains to ensure preparedness of security agencies in emergency situations. DMRC is also looking at raising the station walls and railings for the safety of passengers.
