One of the most widely used and comfortable
modes of transportation system is the train, but occasionally,
accidents occur due to collisions as well as other reasons.
It is very difficult to stop such collisions because of speed
of moving trains, which need a lead distance to stop. Collisions
happen due to human errors and/or faulty equipment. We jointly
with KRCL took up an Intensive analysis of major accidents
that have occurred in India. The functional requirements of
the clients and operational safety procedures have been fully
considered for designing the logics.
Based on the concept and domain knowledge provided by Konkan
Railway Corporation Ltd, we developed the networked Anti-Collision
system which is a customized version of RAKSHA KAVACH™
product, using Global Positioning System, Radio Communication,
and Application Logics and inter-facing these with an auto
breaking system in the train, conforming to the functional
requirement specifications laid down by Konkan Railway Corporation
The product has been successfully developed for deployment
after initial and extended field trials on the Amritsar-Jalandhar
Section of Northern Railway using 125 ACDs of different types.
On 20th January'2004, the then Honorable Railway Minister
launched the project at Kishangunj, Bihar on a 1730Kms rail
route on the Northeast Frontier Railway route.
We have successfully completed ACD deployment over 736Kms
on the Konkan route and another 1730Kms on the Northeast Frontier
Railway routes is nearing completion. The above routes consist
of some of the most inhospitable rail sections of the country.
The work involved surveys of the tracks, erection of towers,
manufacturing and supply and commissioning of networked ACD
system and customizing the same.
The system consists of Loco ACD with a console (message display)
for the driver (in each Loco Engine), Guard ACD with remote
(fitted in Guard Van), Station ACD with console (fitted in
Station Masters' Cabin), Manned and Unmanned Gates ACD with
hooters and flashers (in each location) and Repeater ACDs
(fitted at locations having obstructions in radio communication
such as hilly areas) which work in concert to prevent the
following kinds of collisions and accidents.
- Head on collisions
- Rear end collisions
- Collisions due to derailment
- Collisions at the level crossing gates
- Collisions due to inactive crew
- Collisions due to train parting
- Collisions in non–Interlocked Stations
- Accident due to Landslides and Falling Boulders
We plan to add the following additional features for ACDs by integrating with special sensors:
- Detecting Overflowing rivers and bridges
- Detecting Displaced tracks
- Detecting Accidents in Tunnels
Since, Anti Collision System are cost effective solutions
to prevent train collisions, and is not dependant on the existing
infrastructure, It can be easily modified to work with suitable
modifications on any railway
network in the world.
Advantages of Networked ACD System
Auto Acting Devices
The Networked Anti-collision system consists of a Network of Auto Acting Micro processor based communication devices that will trigger off automatic brakes of trains whenever a collision like situation would arise.
Designed for preventing collisions
The system is specially designed to prevent collisions at the stations, mid sections, level crossings, and parallel sections.
Provide distance scan
The system provides a distance scan over a range of nearly 3 KMs, thereby detecting collision like situations, if any, take appropriate action to prevent collision, by constant data communication- interchange in the area.
Communication based Control System
Through data communication, Loco ACD in the Locomotive, Station ACD in the station, Level crossing Gate ACDs (manned as well as unmanned level crossings), are networked and are constantly in communication with each other within a range of 3 KMs. If the communication range is reduced due to obstructions, it is extended by providing Repeaters along the track.
Does not interfere with Normal Traffic
Here in all cases, even though movement of train is controlled through data communications, where in standard rules are implemented to avoid collision on railroads, the ACDs do not interfere with normal operational procedures and traffic. In normal conditions, the driver is still solely responsible for the safety and control of the train, along with the guard.
