Essential Power Supply (DG Set)
  • Standby generator will be provided at all stations to provide essential low voltage power supply to the essential loads that can maintain the operation in a safe environment in the event of the failure of the normal station power supply. The non-essential loads will be shed before the generator takes up the loads
Emergency Power Supply (UPS)
  • Uninterrupted Power Supply (UPS)will be provided with batteries at the stations to provide emergency low voltage power supply to the emergency loads that can maintain the operation in a safe environment in the event of the failure of the normal station power supply until the standby generator can take over.
Earthing System
  • The earthing system designed in accordance with Indian TN-S system shall be provided for the purpose of safety from electric shock for personnel, operation safely and to prevent stray current.
  • Main earth Mat system shall be provided for each stationto achieve the earthing resistance of less than 1 ohm for Electrical system equipment and Clean Earth Mat System shall be provided in for each station to achieve an overall earth resistance not greater than 0.5 ohm for Extra Low Voltage system equipment such as S&T, AFC and BMS system.
Low Voltage Cables
  • All low voltage cables, wires&control cables shall be XPLE, Flame Retardant Low smoke (FRLS) PVC insulated cable.
  • Cables for Emergency Services shall be of Fire Survival (FS) type cables
  • All LV cable conductors shall be of Copper.
Building Management System
  • Building Management System is for controlling and monitoring functions of Station MEP Equipment such as Lighting, Lifts and Escalators to provide better comfort for the Passengers of each station by effective utilization of Ventilation &Air Conditioning andElectrical installations.
  • Passenger Elevators suitable for Physically challengedwith SS car body, machine room-less, Electric Tractionwith Gear less motor having VVVF Control shall be provided in all stations from Street level to concourse level and concourse level to platform level.
  • Escalators suitable for semi-outdoor installation shall be provided in all stations. Steel Escalator is planned from Street level to Concourse Level and Glass Escalator (lighting below hand rail) from Concourse level to Platform level



Fire detection and Suppression System
  • Fire Detection & Alarm System of Analogue Addressable type shall be provided in all stations to detect the presence of fire and initiate the Fire Suppression action through Fire Hydrant system and Automatic Sprinkler System to provide protection from Fire.
Clean Gas flooding fire suppression system
  • Gas Flooding Systems will be installed in all Stations to protect critical Rail System equipment from fire
Co2 based internal gas suppression system
  • CO2 Fire trace system is provided to extinguish the fire inside the Critical Power Supply Panels which are located in Sub-Station.
Portable first-aid fire extinguishers
  • The extinguishers will be used to extinguish fire in the early stage to avoid major losses. Fire extinguishers are easy to handle.
  • Types of extinguishers installed in each station are Carbon Dioxide (CO2), ABC & DCP type Fire Extinguishers
Photo luminescent safety signage
  • The photo luminescent safety signage glows in darkness which will guide the safe escape of occupants even in case of the power supply failure. This can be also useful to find the location of the Fire fighting appliances in case of emergency even in darkness.



Air Conditioning System
  • Critical Rooms such as Station control Room, Ticket Office, UPS & Battery, Telecom &Signaling equipment room which are related to Rail System operation are provided with High wall split Units for air conditioning.
Ventilation System
