    At 359 metres, rail bridge over
    Chenab will be world’s highest

    May 30, 2011, 01.42am IST TNN [
    Mahendra Kumar Singh ]
    The world’s
    highest railway
    bridge -- five
    times the height
    of Qutub Minar
    and 35 metres taller than
    Eiffel Tower -- will come up
    over the Chenab river on the
    under construction rail link to
    the Kashmir Valley.
    SRINAGAR: The world’s highest
    railway bridge -- five times the
    height of Qutub Minar and 35
    metres taller than Eiffel Tower --
    will come up over the Chenab
    river on the under construction
    rail link to the Kashmir Valley.
    The bridge will rise 359 metres
    over the Chenab, 65 km from
    Katra, on the 73-km Katra-
    Dharam section of the ambitious
    Udhampur-Srinagar-Baramulla
    Rail Link Project. This section
    alone will cost around Rs 5,005
    crore.

    Konkan Railway Corporation,
    with experience of building 179
    major bridges on the path-
    breaking rail link through the
    Konkan region, will execute this
    particular section.
    The 1,315-metre bridge will use
    up 25,000 million tonnes of steel
    and will be an engineering
    marvel.“Work is going on in full
    swing,” said Rajesh Agarwal,
    general manager, Konkan
    Railways.
    The world's tallest rail bridge is
    on France's Tarn river and its
    tallest pillar rises 340 metres
    while the actual height at which
    trains run on the bridge is 300
    metres. "The Chenab bridge will
    be the highest in the world,"
    Northern Railway chief
    administrative officer Chahatey
    Ram said.
    Observing that wind speed at the
    height of 359 metres may go up
    to 266 kmph, the engineers have
    decided not to allow trains
    crossing the Chenab bridge if the
    wind velocity is more than 90
    kmph. The railways has designed
    the signalling system at the
    bridge in such a manner that it
    shows the stop light
    automatically when wind speed is
    more than 90 kmph.
    Considering the inaccessible
    terrain of the Himalayan
    mountains, the bridge will get a
    special coat of paint with a life
    span of around 35 years to
    protect it from the tough
    weather.
    Besides the steep topography
    and fragile geology, engineers
    constructing the Katra-Dharam
    line also have to factor in
    security concerns. While Railway
    Police (GRP) and Railway
    Protection Force provide security
    to engineers and workers
    implementing the project, the
    support of locals is coming in
    handy.“Only two incidents of
    terrorists targeting the project
    have been reported since work
    was started,” said Shovkat Malik,
    SSP, GRP, Kashmir Range.
    The railways has constructed a
    helipad to transport construction
    material and equipment. For the
    73-km section which involves
    construction of 63 km of tunnels
    and 7.5 km of bridges, Konkan
    Railways is constructing 176 km
    of roads to access the project
    sites. Railways has already
    constructed 104 km of roads
    which is giving connectivity to
    remote villages which were till
    now inaccessible.
