Eco-design : designing trains that protect the
environment

ALSTOM has committed to integrate environmental factors into
the design of its products to control and reduce their
environmental impact throughout their lifecycle, from
manufacture to recycling. This approach has allowed ALSTOM
to:

  • Improve the recyclability of its trains thanks to the use
    of reusable materials such as steel, aluminium or copper.
    ALSTOM also carries out research to use bio-materials,
    originating from renewable resources such as wood or hemp.
    This recyclability has now reached a minimum of 85% and can
    go as high as 95.2% for the TER 2NNG double-deck regional
    train.
  • Reduce noise pollution both inside and outside the train
    by using insulating materials and by optimising the
    wheel-rail contact through the use of acoustic
    shock-absorbers. This approach has reduced the interior noise
    level in the ALSTOM METROPOLISTM metro by 7 decibels over 10
    years.
  • Reduce energy consumption. The use of composite
    materials, improved traction system efficiency and
    articulated train architecture has allowed for a 10%
    reduction of mass and energy consumption.

    On-board energy systems: supporting urban integration
    Today the tramway can no longer simply be considered
    as a means of transport. For local authorities, it is also a
    means to think about their town in new ways and at the same
    time add value to their architectural heritage. To foster
    this trend, ALSTOM is committed to conducting research and
    development on solutions that allow the tram to blend
    harmoniously into its urban environment.

    ALSTOM is currently the only producer pursuing the
    development a range of totally innovative
    wireless solutions that represent a real
    technology breakthrough with respect to classical
    power-supply methods.

    • APS (Alimentation Par le Sol : ground-level power
      supply)
      is a power supply system that makes use of
      a third rail embedded in the tracks. The Bordeaux
      Metropolitan Area is the first city in the world to have
      opted for this totally innovative technology.
    • The battery is an autonomous on-board
      solution that allows the tram to operate in urban areas
      without overhead cables over distances under one kilometre.
      This technology was developed as a world-first on
      ALSTOMs CITADISTM tram in Nice: the historical
      character of the Masséna and Garibaldi squares can
      thus be preserved.
    • The inertia flywheel allows the tram to
      generate its own completely renewable power by recuperating
      the energy produced during braking. The inertia flywheel,
      developed in partnership with CCM (Center for Concepts in
      Mechatronics) and tested under real-life operating
      conditions since 2005 on the ALSTOM CITADIS tram in
      Rotterdam, innovates through its use of electro-magnetics.
      The system consists of a rotating mass positioned on the
      trams roof, which functions like a spinning top. The
      kinetic energy stored during braking is then returned to
      the traction system at the next acceleration. The system is
      charged whenever the tram brakes or via an
      additional fast charging system at each station. The use of
      the energy stored on board therefore allows a considerable
      reduction in electrical power consumption, with a system
      lifetime that is equivalent to that of the tram
      itself.

    Information and video surveillance: ensuring
    passenger security

    For ALSTOM, innovation for people also means strengthening
    passenger security.

    ALSTOM has therefore developed a unique on-board surveillance
    and passenger information system: AgateTM e-Media. More than
    just a video-surveillance security system, AGATE e-MEDIA also
    offers a high added-value service for passenger
    communication. Passengers receive real-time information on
    trip time, station waiting time, repairs, line incidents,
    etc. The operator can also use this system to promote its
    products and services or as interactive advertising space.
    These are all aspects that increase the comfort and
    attractiveness of public transport.

    ALSTOM is also working on a research and development project
    in the area of passenger security: surveillance by passenger
    behaviour analysis. This technology allows the detection of
    abnormal situations (shouts, attacks, fights, etc.) inside
    the cars thanks to latest generation on-board equipment
    (cameras, microphones, loudspeakers, GPS receivers, etc.).
    The operator can therefore intervene real-time and take
    appropriate measures according to the situation.

    Design and comfort: making the train a living space
    for all

    The quality of life on board is a priority for ALSTOM.
    Everything is done at the design stage to make the trip more
    pleasant and comfortable: ergonomic seats, materials, new
    colours and lighting.

    A frontrunner in accessibility for reduced-mobility
    passengers, ALSTOM addresses train and inter-car access right
    from the design phase: more access doors, low floors along
    the length of the train, no gap between platform and train
    thanks to  thresholds and mobile steps. Everything is
    designed to facilitate life on board and to make the train a
    living space for all:

    • Specific equipment: toilets, lifts, dedicated areas,
      grip bars and ramps designed and positioned to promote flow
      and movement.
    • Access to information: audio messages, dynamic line
      maps, sound and visual alarms for door closing, flashing
      door buttons that can be identified by touch.

       

    To improve passenger comfort further and to prepare for
    future trends, ALSTOM has teamed up with RCP, a design firm,
    to develop the sensorial design in trains. This approach
    consists of harnessing all five passenger senses through the
    feel of materials, colours, sounds, odours, temperature or
    lighting. Based on an overall assessment of passenger
    perception for all sensorial aspects, ALSTOM and RCP then
    define specific work areas for existing equipment such
    as:

    • Tactile perception of grip bars to make them more
      pleasant to the touch.
    • Auditory perception of door opening/closing sound
      alarms.
    • Olfactory perception of textiles and seats, which
      absorb odours and release perfumes.
    • Visual perception by adjusting colour associations and
      light variations.
