Driverless Metro from the Louvre to Arc de Triomphe

15.03.2012
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: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
