9. METRO CARS
Metro’s are one of most affordable, environment friendly, safe and a comfortable mass rapid transit system.
Metro cars have state-of-the art technology with high reliability, availability and maintainability.
Metro car interiors are world class and are designed for a pleasant ambiance and also ensuring,
Passenger Comfort
Passenger Safety and
Passenger Security

10. 2. PASSENGER COMFORT
The main features which effect passenger comfort are discussed briefly:
2.1 Air conditioning system (HVAC)
The No.1. feature which provides passenger comfort is the HVAC system and how effective the air conditioning is.
HVAC system are designed to maintain 25°C and 60% RH
Load-weigh signals taken for optimum control
During Design stage CFD analysis are carried out
Air velocities & temperature distribution-EN14750.
Air quality is maintained as per ASHRAE standards

11. 2. PASSENGER COMFORT 2.2 Noise & Vibration levels
Control of noise and vibration is one of the critical issues effecting passenger comfort.
The components that dominantly contributes noise when the :
Vehicle in stationary condition
HVAC (Heating, Ventilation & Air conditioning system)
Main transformer
Air compressor
Vehicle In Running Condition
Wheel rail interactions
Track irregularities
Traction motors
Gear boxes
Braking

12. 2. PASSENGER COMFORT 2.2 Noise & Vibration levels
Since all noise sources are located outside carbody, the passenger comfort greatly depends effectiveness of noise insulation provided
Some of Noise mitigating features provided are
Floating floor
Gangway design – (2 piece construction with double skin bellows)
Door leaf construction
Interior FRP – Semi sandwiched Nomex Honey comb panels
Proper sealing of Doors
Windows – Insulated Glass units
Insulation

13. 2. PASSENGER COMFORT 2.3 Amenities provided HVAC Seats
Grab-poles and rails
Passenger information system
Public address system
Passenger alarm devices
Gangways
Dedicated Wheelchair space
Mobile chargers etc.

14. 2. PASSENGER COMFORT 2.4 Ergonomics
All amenities are designed such that 95th percentile of Indian population can access the Interior facility – like grabpoles, Grab rails & Straphanger without any inconvenience

15. 2. PASSENGER COMFORT 2.5 LED Lighting
LED’s are the most efficient lighting system
Long life and low power consumption.
Provides illumination of 300lux at a height of 1.0m above floor level.
Auto dimming feature for optimum power consumption
Fire retardant polycarbonate diffusers are used to avoid glare
Meets IEC for shock and vibration.
Fittings meet IP52 /54norms

16. 3. PASSENGER SAFETY 3.1 Interior Passive Safety Design
The interiors are designed considering interior passive safety. The objectives of this design is to minimize injury to passengers in case of collision or derailment.
By following this design, it also help us to reduces the level of minor injury through trips, slips and falls, that can result from unexpected vehicle movements such as emergency braking or track irregularities
Features:
All mounting hardware's are concealed or flush with surface
All edges have liberal radius
Longitudinal seats provides better containment of passengers, reducing the velocity of secondary impact
No projection of floor
No Openings to avoid entrapment of fingers or foot
Anti skid floorings

17. 3. PASSENGER SAFETY 3.2 Passenger Saloon Door System
Automatic door systems are provided which allows only platforms side doors to be opened ensuring passengers safety
Traction will not be initiated until all doors are closed and proven
During door closing if any obstruction is sensed, the door moves back immediately permitting clearing of obstruction
Door indication lamps/chimes are provided to caution the passengers during door operation

18. 3. PASSENGER SAFETY 3.3 Fire Safety
Metro cars are designed for Fire safety with a system approach
Material selection
Fire detection
Suppression systems
Means of evacuation to a safe place and time taken
All non-metallic materials meet flammability, toxicity and smoke emission limits (FST) as per BS 6853 Cat 1a/1b or equivalent
Floating floor has been designed to provide a fire barrier a minimum of 30 minutes duration
Total Fire heat Load not to exceed MJ
Fire detection in Cab
Fire suppression by Fire extinguisher

19. 3. PASSENGER SAFETY 3.4 Emergency evacuation
3.4 (a). End evacuation - Cab front emergency door

20. 3. PASSENGER SAFETY 3.4 (b). Side evacuation - Passenger saloon doors.
EXTERNAL EMERGENCY RELEASE HANDLE
