Driverless Metro from the Louvre to Arc de Triomphe

The Paris transport authority (RATP) is currently switching the Metro's Line 1 to fully automatic operation - which also means driverless.

Siemens is responsible for the modernization of the automation technology. The new system is more energy-efficient in operation and makes it possible to shorten the intervals between trains from 105 to 85 seconds. Line 1 trains carry up to 725,000 passengers a day, making it the most heavily traveled Metro line in Paris.

The reason Line 1 carries so many passengers is that it passes sightseeing attractions like the Louvre and the Arc de Triomphe. It would be unimaginable to even briefly interrupt service on this line, which is 17 kilometers long, so the switch to automated operation is being carried out without disrupting service.

That means installation of the control technology and the telecommunication system, fitting the rail vehicles and equipping the new control center must all take place in parallel to normal operation.

The Siemens rail automation unit's solution was to perform the work at night. At present, the old trains are being replaced, one after another. In March 2012 there were 14 driverless trains on Line 1. By early 2013 all 49 new Metro trains are to be equipped with automation technology, bringing service up to full transport capacity.

The train frequency can be flexibly adjusted as needed. Special platform screen doors ensure safety at the stations. The new trains use the Trainguard MT safety and control system, which is in service in many of the world's big cities. A subway line in New York City is also soon to be equipped with the system.

The new control system boosts energy efficiency and improves reliability: The previous system had to be left on when, for example, the trains were parked at night at a depot, in order to continually check and save data related to the vehicles' position and status. After the new system is re-started it automatically determines the position of the train by means of intelligent communication between the train and the wayside equipment.

That means it can be turned off overnight, which saves energy. And should a system go down, the train can then compute its own position on the track and also determine if another train is nearby. If the track is clear, the train automatically proceeds safely, without human hands at the controls, to the next station, where service engineers can inspect it for a possible fault. This minimizes delays due to technical malfunctions, particularly in situations where trains run very frequently.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
