Trial run for india’s first every metro train equipped to run on ‘unattended train operation’ mode flagged off

The trial run of India’s first ever Metro train, equipped to run on the
‘Unattended Train Operation’ mode, was ceremonially flagged off today by the Union Minister for Urban Development, Sh. M. Venkaiah Naidu and Delhi
Chief Minister, Sh. Arvind Kejriwal.

The inaugural train moved out from the Mukundpur depot and travelled up to the Majlis Park Metro station of the Majlis Park – Shiv Vihar Metro corridor of Phase 3 (Pink Line). The new trains, with extremely high levels of automation, will now undergo rigorous trials to ensure that they are ready for smooth operations after the commissioning of the new corridors Initially, train operators will run the trains, but gradually, driverless operations (on the Unattended Train Operation (UTO) mode) will be possible


In addition, a green Receiving Sub Station (RSS) for the power requirements of the Majlis Park – Shiv Vihar corridor was also inaugurated at Mukundpur The RSS has been entirely designed as a green structure with features such as solar power plant, rain water harvesting, sewage water treatment facilities etc

Features of the new Metro trains:

1.      *Fixed six car trains with 67% Motor cars instead of 50% in earlier trains, ie, each six car train will have four Motor cars and two trailer cars*

§  Higher acceleration resulting in 10% increase in scheduled speed.
§  Higher regeneration resulting in lower energy consumption by 20%.

2.      Wider carbody of 3.2m wide against earlier design of 2.9m wide carbody on Standard Gauge.



3.      Maximization of Passenger carrying space

·          Equipments placed beneath the Seats to release additional space
(2.0 sqm) for 12 more passengers.

·         Wider gangway (1120mm as compared to 1030mm).

·         Increased space in Unattended Train Operation (UTO) mode (approx 5.0 sqm), Overall approx 40 more passenger in the driver’s Car (since the driver’s cabin would be removed in case of ‘driverless’ operation).

4.      Passenger Comfort and Convenience

·         Provision of Wi-Fi internet facility in trains.

·         Digital Route Map- 37 inch LED type, fully programmable with
dynamic change of split screens.

·         Fully programmable LCD screens with videos, graphics, animations,
real time video streaming.

·         Improved air circulation.

·         Charging Point + USB port facility.

·         Provision of Lumber support/Backrest near wheel chair area.

·         Redesigned Grab rail/ pole layout.



5.      Noise Reduction Measures

·         Improved Floor Design with high density ceramic wool insulation

·         Wheel with noise dampers

·         Curve actuated WFL & HPF for reducing squealing noise on curve.



6.      Aesthetic  exterior/Interior design with:

·         Aero Dynamic front profile with wide Wind screen glass with front
evacuation arrangement.

·         Aesthetically designed energy efficient LED head lights and
marker lights.

·         Ceramic Coated Aluminum Interior Panel with superior finish,
Improve floor covering & Wheel chair marking on floor, Colourful Passenger
Seats.



7.      Energy Efficient Design

·         Higher Regeneration.

·         LED saloon lights with automatic dimming facility based on
ambient light.

·         Inverter controlled energy efficient HVAC System with eco
friendly R-407C refrigerant.



8.   Designed for Unattended Train Operation (UTO) mode of operation

·         Remote Control of Trains: Starting and stopping, acceleration &
braking, operation of doors and handling of emergencies are fully automated
without any on board staff.

·         Two way communication between Operation Control Centre (OCC) &
Train.

·         Live streaming from inside car CCTV system to OCC & vice versa.

·         Obstruction Deflection Device (ODD) is installed to push away
small obstructions on track to avoid derailment.

·         Additional 2 Front Facing Cameras (DM)+ 1 Detrainment Camera (DM)



Details of the trial run:

Since, these Metro trains are being introduced in Delhi Metro for the first
time, they will be put through stringent trials to ensure that smooth
services are provided to the commuters after the commissioning of the lines.uring the trial runs, the interaction of the Metro train with physical infringements (civil structure) will be checked to ensure that there is no physical blockage during the movement of the train on the track


Later on, in stages, the new signalling technology to be implemented on this corridor – Communication Based Train Control (CBTC) will also undergo rigorous testing.

In addition, the response of the train at different speeds, braking of the train and the interconnection with the Operations Control Centre (OCC) will also be monitored during the trials. The behavior of the track system and the Over Head Electrification (OHE) will be checked repeatedlybr> Green Receiving Sub Station at Mukundpur:

A Receiving Sub Station (RSS) was also inaugurated today at the Mukundpur
depot which will cater to the power requirements of the Majlis Park – Shiv
Vihar corridor. The sub-station has been designed entirely as a green
building with a host of environment friendly features. A similar green
sub-station is already operational in Faridabad. The green features of the
Receiving Sub Station are:

·         Solar power generation capacity of 31.2 KWp

·         Rain water harvesting for water conservation

·         Sewage water treatment plant to make it a ‘water neutral
sub-station’

·         Low CFC refrigerant and inverter compressor type VRV
air-conditioning instead of split air-conditioning for lesser power
consumption

·         LED lighting and Bureau of Energy Efficiency labeled electrical
equipments

·         Urinal sensors for water conservation

·         Water meters to monitor water consumption

·         Landscaping to preserve top soil around the sub-station
