six
initiatives of his Directorate namely TALGO Trials, TRINATRA and MAGLEV
Technology, EoTT, bio-toilets and new train products
The
EoTT equipment is used to establish communication between Locomotive driver and
the last vehicle of the train to see that the train is running with all
coaches/wagons as a “complete” train.
Member,
Rolling Stock(earlier called Member Mechanical), Railway Board Shri Hemant
Kumar gave details of six initiatives of Indian Railways pertaining to his
Directorate at a press conference held in Rail Bhawan today i.e. 09.08.2016.
The briefs of these six initiatives are given as below : -
Ø Brief
about bio-toilets and green train corridor : -
In
order to contribute to mission ‘Swachh Bharat Abhiyan’ launched by Hon’ble
Prime Minister of India, Ministry of Railways have taken up a mammoth task of
providing human discharge free bio-toilets in all its coaches and the same
would be completed by September 2019. With provision of bio-toilets in all its
coaches discharge of human waste from trains on to the ground would be completely
stopped which in turn would help in improving cleanliness and hygiene. Ministry
of Railways have already provided 43,000 bio-toilets in its coaches till 31st
July, 2016 and in the current financial year, it is planned to fit additional 27,500
bio-toilets.
Indian
Railways in its commitment to provide hygienic environment to passengers and to
keep station premises/tracks clean, have developed environment-friendly
Bio-toilets for its passenger coaches. The technology has been developed
jointly by Indian Railways (IR) and Defence Research & Development
Organization (DRDO) for railway passenger coaches through an MoU. This
environment friendly, low cost and robust technology, is the first of its kind
in Railway Systems in the world. In the bio-toilet fitted coaches, human waste
is collected in tanks below the toilets and the same is decomposed by a
consortium of bacteria.
In
order to have visible benefits in terms of cleaner environment owing to
provision of bio-toilets in coaches, Rameswarm-Manamadurai (114 Kms) was
indentified to make it Green Train Corridors- free from human waste discharge
from trains. Accordingly, 10 passenger trains consisting of 286 coaches moving
over this section have been provided with bio-toilets. This section was
formally inaugurated as Green Train Corridor on 24.07.2016. After
Rameswarm-Manamadurai, Okha-Kanalas Junction(141 Kms), Porbandar-Wansjaliya (34
Kms) and Jammu-Katra(78 Kms) would also be taken up for making them free from
human waste discharge from trains. For this around 35 trains consisting of
nearly 1110 coaches would be further provided with bio toilets and the work is
underway. These sections and stations were chosen, because the number of trains
originating and terminating at these stations and sections are few, thus making
it operationally easier and faster to make them human-discharge free.
Okha-Kanalas
section is targeted for conversion to Green Train Corridor by the end of
September 2016, whereas Porbandar-Wansjaliya is targeted for conversion by
October 2016. For Jammu-Katra section, a total of 24 rakes of 14 trains
consisting of around 450 coaches need to be provided with Bio-toilets and the
same would be targeted for completion by March 2017.
Ø Brief
about new types of train products : -
In
order to make train journeys a more delightful experience, Indian Railways have
been taking numerous initiatives. Minister of Railways, in his Budget Speech
2016-17, had announced a number of new categories of train services or coach
such as Tejas, Humsafar, Antyodaya and Deen Dayalu coaches. Introduction of
these train services/coaches is being followed up in mission mode.
For
General Second Class passengers, potable water through Water filtration system,
cushioned luggage racks, additional hand
holds in doorway area, J hooks near longitudinal luggage racks for hanging
carry bags, bio-toilets, water level indicator, Toilet
occupation indication display board, Enhanced mobile charging facility, Fire
extinguishers etc. are some of the amenities added in Deen Dayalu and Antyodaya
train coaches. Besides, for the first time, Indian Railways would try out
operation of Antyodaya trains with Locos at both ends for faster acceleration
and deceleration and for expeditious turnaround at terminals. 5 Antyodaya rakes
have been planned for introduction in the current year and the first rake is
expected by October 2016. Around 700 Deen Dayalu
coaches are planned for introduction in various trains in the current year. First
Deen Dayalu coach has already been launched by Hon’ble MR on 19.07.16 at NDLS
station.
Similarly,
Humsafar trains consisting of AC 3-Tier coaches only would have
additional facilities such as GPS based
Passenger information display system to inform passengers about arriving
station, Passenger announcement system, Fire and Smoke detection system for
enhanced fire safety, Mobile/ laptop charging points, Integrated Braille
displays for the aid of visually impaired passengers, Improved aesthetics with
new interior and exterior colour scheme etc. While 10 Humsafar rakes are
planned for introduction in the current year, first such rake is expected by
September 2016.
Tejas train coaches
would be the future of train travel in India with modern amenities and gadgets
provided to make train travel not only comfortable but delightful too. Tejas
coaches would have ergonomic seating with improved
cushioning and upholstery, Automatic doors, Infotainment system, GPS based Passenger information display system, Dust
sealed gangways, Fire
and Smoke detection system , CCTV system, concealed LED lighting, adjustable
reading lights, Passenger announce ment system,. Vending machine, Mobile laptop
charging points, enabling provision for on-board Wi-Fi facility, Integrated
Braille displays, individual Magazine bags, bottle holders, snack table, Bio-Vacuum
toilets, Sensorised taps, flushing system, hand driers, tissue paper dispenser
and soap dispenser for touch less experience of toilet use, water
level indicators, Accessible dustbins with higher capacity, Digital Destination
Boards outside the coach for train and coach information to the boarding
passengers etc.. 3 Tejas AC Chair Car rakes have been planned for introduction
and the first rake is expected by February 2017.
One
Uday train service is planned for introduction in the current year with LHB AC
Double Decker coaches.
Ø Brief
on Trials of Spanish Train TALGO : -
Talgo is a Spanish firm manufacturing Semi high
speed (160-250 kmph) and high speed (350 kmph) passengers trains. Talgo trains
have been successfully running in many countries with high safety records.
Talgo coaches are light weight aluminum bodied
coaches with special features like articulated coupling between coaches, wheel
sets located between adjacent coaches, independent wheel system, short guide
axles with neutral tilting. These features make these coaches to travel faster
on curves with approximately 20% higher speed in comparison to conventional
coaches. Because of low weight faster acceleration and deceleration is also
possible thereby reducing the travel time and increasing the average speed.
With an objective to increase the speed of
Mail/Express trains on its networks, IR decided to conduct trials of Talgo
coaches to validate their speed potential and access saving in time between New
Delhi and Mumbai without any investment on the fixed infrastructure. M/s. Talgo
has brought 9 coaches for free of cost trials with no commitment from Indian
Railways. Speed trials were conducted between Barailey and Moradabad section of
Northern Railway upto speed of 115 kmph.
After successful completion of these trials high
speed trials upto a test speed of 180 kmph were conducted between Mathura and
Palwal section of NCR. The trials were found successful.
After the speed trials time saving trials have been
started to validate the simulation done by M/s. Talgo. Total four runs were
planned at a speed of 130, 130, 140 and 150 kmph. Two runs have already been
conducted on 1.8.2016 and 5.8.2016. The trials have been successful and actual
running results were better than the simulation results. In first run train
could not run as per schedule due to heavy rain between Surat and Mumbai due to
wash out of tracks. 3rd run has started today and 4th run
will be on 14.08.2016. It is expected that time saving of 4 hours will be
achieved between New Delhi and Mumbai over the existing Rajdhani Express.
Ø Brief
about Safety Device - TRI-NETRA - Terrain imaging for diesel dRivers INfra-red,
Enhanced opTical & Radar Assisted
system
Ministry
of Railways, Railway Board has initiated a proposal to install TRI-NETRA
systems on locomotives for enhancing the vision of Locomotive Pilots in
inclement weather. TRI-NETRA stands for - Terrain
imaging for diesel dRivers INfra-red, Enhanced
opTical &Radar Assisted system.
TRI-NETRA system shall be made up of
high-resolution optical video camera, high sensitivity infra-red video camera
and additionally a radar-based terrain mapping system.
These
three components of the system shall act as three eyes (Tri-Netra) of the
Locomotive Pilot.
TRI-NETRA is designed to “see” the
terrain ahead of the running locomotive during inclement weather by combining
the images captured by the three sub-systems and to create a composite video
image which shall be displayed in front of the Loco Pilot on a computer
monitor.
During fog, heavy rain and also during
night, the locomotive pilots face serious challenges in looking out ahead to spot
any obstruction on the track such as vehicles which get stuck while crossing
the track or trees or boulders which have fallen across the track etc. Because
of the heavy momentum of the running train, the train driver has to always
adjust the speed of the train such that he or she can stop the train on
visually seeing the obstruction. In fair weather and in daytime, this is not a
problem since train driver has a clear view of the track ahead. But in poor
visibility, he has to reduce the speed suitably so that the brakes can be
applied in time to stop the train without hitting the obstructions.
This is where TRI-NETRA will come into
picture and give the locomotive pilot a clear view of the track ahead in bad
visibility conditions so that he can apply brakes well in time. Conversely, he
can speed up the train even in poor visibility if the TRI-NETRA system shows
that the track ahead is clear of obstruction. The system shall also map the
terrain ahead so that the driver knows when he is approaching a station or a
signal. TRI-NETRA will enable the Locomotive Pilot to “see” objects from upto
one kilometer away on straight track during inclement weather.
The concept of TRI-NETRA was developed
by Development Cell under the guidance of Member Mechanical, Railway Board while
brainstorming on how to use the technology employed by fighter aircrafts to see
through clouds and operate in pitch darkness and the technology used by naval
ships in mapping the ocean floor and navigating in the night. Such an “assisted
vision” system is not available readily in any of the advanced railway systems
but the manufacturers and technology partners who develop components of such
systems for defence are very excited with the concept. “Such systems have not
been used for peacetime applications and we are excited that Indian Railways
have thrown such a challenge at us” said one of the foreign specialists who
develops such systems for fighter aircrafts. There has been very enthusiastic
response to this Expression of Interest (EoI) published by Railway Board and
number of companies from Israel, Finland, USA and Austria have expressed
interest in developing such a system.
Ø Brief
On Communication Equipment - End Of Train Telemetry (Eott)
·
|
·
There is a transmitter fitted on a
locomotive and a receiver that is fitted on the end of the last vehicle.
·
The
transmitter and the last vehicle receiver exchange signals periodically at
regular intervals to ensure that the complete train is running as “Ïntact
train”.
·
If there is a break in the communication
between the two units, the driver gets a signal that the train has parted.
·
The
transmitter unit which is fitted at the end of the train’s last wagon is
connected to the brakes and it bleeds the Brake Pipe air and applies brakes to
the broken away portion of wagons of the train so that they do not collide with
the front portion.
·
A project has been sanctioned for
purchase of 1000 systems at an estimated cost of Rs. 100 Crores.
·
Specifications of the equipment have been
prepared and tenders shall be called shortly.
Ø Brief
on Levitation based Trains (MAGLEV)
·
Levitation Technology is being used in the world in
many different ways – Hovercraft that levitates on air-cushion, Maglev etc.
·
“MAGLEV “stands for MAGnetic
LEVitation.
·
The MAGLEV floats above the track on a
“Cushion” of magnetic field.
·
Magnets on the track push and lift the
MAGLEV up in air by about 1 inch to 6 inches.
·
These
“track” magnets are controlled by a computers which keep shifting forward the
magnetic force of the “track” magnets so that the MAGLEV is pulled forward.
·
Maximum speed achieved is 500 km/h.
·
One commercial installation is in China
in Shanghai (appx 38 km of MAGLEV) and is currently running commercially.
·
New technologies are coming up to
decrease the power consumption of magnets that lift the MAGLEV by using
liquid nitrogen or similar gases..
·
Holy Grail of Maglev magnets is
superconducting magnets which consume very little current. Currently, super
conductive magnets requires very low temperatures to be maintained in the
magnet, however rapid research is going on to make high temperature
superconductors.
·
EoI document has been floated on 4th
August 2016 and shall open on 6th September 2016.
