Efficient Subway Train Almost Entirely Recyclable

30.01.2012
The new Inspiro from Siemens is currently one of the lightest subway trains in the world.

Engineers at Siemens Mobility relied on a lightweight design with aluminum profiles while developing the rail vehicle.


The highlight at the Siemens stand at the UITP in Dubai: a mock-up of the Inspiro metro.

As a result, a six-car train is around six tons (or more than three percent) lighter than a comparable unit. The trains also use less energy and can transport more passengers.

Transit companies have the option of equipping the trains with additional energy-saving systems, such as those that control air conditioners with carbon-dioxide sensors or utilize energy-efficient LED lighting systems. What’s more, the Inspiro can be almost fully recycled after its roughly 40-year service life. The metro operating company in Warsaw will begin taking delivery of the first 35 Inspiro trains in the fall of 2012.

Numerous measures were undertaken to reduce the weight of the Inspiro. The front end of the cars alone, which houses the couplings, weighs 500 kilograms less than before. Its design is based on the use of light aluminum profiles. To identify areas in which fewer materials could be used without limiting functionality, the entire car body was computer analyzed by means of the finite element method.

Certain components in the cars themselves were made as multifunctional as possible — for example, parts of the ceiling also serve as cable ducts. In a further effort to reduce weight, air ducts are made of light textiles rather than the metal previously used, while a new type of cork-aluminum floor weighs 30 percent less than before, acts as a noise dampener, and also provides better heat insulation. Measures taken into account as early as the design phase form the basis for the train’s extremely high recycling rate of 95 percent, which Siemens Mobility has already demonstrated in the Oslo subway.

The Inspiro serves as a platform for subway trains that meet the different standards prevalent throughout Europe. The trains can consist of between three and eight cars and be equipped with different motors. In addition, the length, width, and height of the cars can be varied in line with existing infrastructure like tunnels and subway platforms. The Inspiro concept, which also reduces development times and costs, is part of Siemens’ Environmental Portfolio, with which the company generated about €30 billion in sales in 2011.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
