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.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
