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.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
