High
reach pantograph-world record set by Stone India
KOLKATA, India -- The new generation
pantograph developed by Stone
India for the Indian Railways allows an increase in
the highest of the overhead wires (catenary height) from the
standard 6 meters to 7.5 meters-setting the world record for
the High
Reach pantograph for highest catenary for electric locomotives.
Such a device is suitable for locomotives
to be used for running double-stack containers as envisaged
in the upcoming dedicated freight corridors being implemented
by Indian Railways. (enlarge

This will also enable Indian Railways to introduce
double-decker passenger trains in high density suburban passenger
route. The pantographs have already been commissioned successfully
after extensive test by Indian Railways.
Stone
India's innovation makes Indian Railway achieve this
unprecedented feat to become the only railway in the world
to run a train under a 7.5 meter-high contact wire.
The new-design world
record pantograph, developed completely in-house,
has many other added features, such as twin catenary height
of 6 & 7.5 meters, auto upward-force adjustment to improve
effective current collection in adverse conditions, thereby
enabling reduction in energy consumption and allowing trains
to run at much higher speeds.
The new design overcomes the traditional
challenge of balancing a high-reach pantograph in double-stack
container trains moving at a high speed in adverse wind conditions,
hitherto faced by all global suppliers of pantographs.
Stone
India Ltd has not only successfully designed and developed
the improved pantograph in a record time but did it completely
indigenously using its own expertise and with its own R&D
setup using cutting edge simulation tools.
The patented new series named as "Omniversal
Intelipanto" has been supplied when other multinational companies
failed to do so before commencement of the trial by Indian
Railway in East Coast Railways which was witnessed by Japanese
technical delegation.
The success of this design will not
only help saving foreign currency but will benefit Indian
Railways by enabling locomotives to run on electricity instead
of costly diesel. Additionally this opens up the possibility
of Indian Railways even running double-decker passenger trains
in high density passenger routes through further increase
of catenary height.
The Company plans to adopt this design
in all its pantograph and plans to export such world
record pantographs to countries, which propose to use
electric traction for running double-stack container trains
as well as double-decker passenger trains.
Stone
India Ltd, a Kolkata based company, which has been
serving Indian Railways for more than 77 years has pioneered
the introduction of several systems to Indian Railways, including
pantographs, used by the electric locomotives and EMUs. So
far all these introductions have been through technical collaborations
with overseas companies.
This marks the beginning of Stone India's major
self-initiative & achievement to arrive at breakthrough innovative
solutions for customers, which are generally fraught with
skepticism of unachievable goals.
