ICE 4 defies wind and weather
Rail customers expect to be served by trains that function perfectly from the very first day of service. This is particularly true for the new Intercity platform that will be operated by Deutsche Bahn (DB). Expected to account for around 70 percent of revenue, the ICE 4 will be the backbone of DB's future long-distance service.
The ICE 4 in the Climatic Wind Tunnel – Snow, ice, wind, rain and blazing sun
The new Intercity train from Siemens underwent a 12-week comprehensive testing program at Rail Tec Arsenal (RTA) in Vienna. Here, in the longest climatic wind tunnel in the world, the train had to prove that it can operate flawlessly at speeds up to 200 kilometers an hour, at temperatures ranging from minus 25 to plus 45 degrees Celsius, as well as in snow, ice rain or in blazing sun.
Two ICE 4 trains will enter passenger service in the fall of 2016 as part of a twelve-month period of trial operations. Until then, the trains will be subjected to rigorous testing.
Before the first passengers board the train, however, the ICE 4 has to prove that it can operate even under the most extreme weather conditions, in blazing heat as well as freezing cold.
The tests, conducted at the Climatic Wind Tunnel operated by Rail Tec Arsenal (RTA) in Vienna, subject the train to conditions far more stringent than required by European norms.
Deutsche Bahn commissioned supplementary tests that are specifically designed to ensure that the train's heating, ventilation and air conditioning (HVAC) operate faultlessly.
In addition, tests check if the pantograph moves up and down and functions in ice and snow, if the windscreen wiper keeps the driver's vision free, if the doors open and close smoothly, the folding steps function and the toilets operate without problems.
In May 2011, Deutsche Bahn awarded Siemens a frame contract for up to 300 multiple-unit trains. The first series production trains will enter passenger service with the change of the timetable in December 2017. The trains are initially foreseen for service in Germany, Austria and Switzerland.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
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...
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...
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...
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....
