Siemens automates high-speed rail route in Northern Spain


Working as part of a consortium with Thales, Siemens is to supply the signal and control technology for a 50-kilometer section of the high-speed rail route between León and Asturias, as ordered by the Spanish administrator company Administrador de Infraestructuras Ferroviarias (ADIF). The contract encompasses installation of the train protection systems, the central control technology, the communication and video monitoring technology and maintenance of these systems.

The route section known as “Variante de Pajares” runs from La Robla to Pola de Lena in the north of the country, and forms part of the 120-kilometer high-speed line linking León and Asturias.

The contract covers the delivery of train protection systems, the fixed telecommunications systems, the Centralized Traffic Control, auxiliary systems and the access control and video surveillance systems. Installation of the train protection systems will take place in two phases: the first phase provides for commercial commissioning with the ASFA (Anuncio de Señales y Frenado Automático) train protection system provided by Siemens.

Phase two of the project will see the installation of the Thales-supplied ERTMS (European Rail Traffic Management System) Level 2, which enables trains to operate at speeds up to 350 kilometers per hour. Siemens has already equipped a number of Spain’s high-speed rail routes with signal and control technology.

One example is the high-speed line between Córdoba and Málaga, for which Siemens carried out the project planning for, and installation of interlockings, train protection systems, communications technology, the GSM-R mobile radio system and associated components, within three construction phases.

The scope of supply also included LED signals, Type FS3000 audio-frequency jointless track circuits, the ETCS Level 1 and 2 train control system and the Spanish train control system with intermittent signaling and brake monitoring (ASFA).

Signaling and control technologies were also supplied for the high speed line from Madrid to Sevilla, which was the first high speed line opened in Spain in 1992. Siemens has also supplied Trainguard 100 and 200 track and vehicle equipment for the more than 300 kilometers of high-speed track connecting Lérida with Barcelona, La Sagra with Toledo and Segovia with Valladolid.

Im Focus: How Cells in the Developing Ear ‘Practice’ Hearing

Before the fluid of the middle ear drains and sound waves penetrate for the first time, the inner ear cells of newborn rodents practice for their big debut. Researchers at Johns Hopkins report they have figured out the molecular chain of events that enables the cells to make “sounds” on their own, essentially “practicing” their ability to process sounds in the world around them.

The researchers, who describe their experiments in the Dec. 3 edition of the journal Cell, show how hair cells in the inner ear can be activated in the absence...

Im Focus: Climate study finds evidence of global shift in the 1980s

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.

Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...

Im Focus: Laser process simulation available as app for first time

In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.

Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
