According to the "The Rail Journey 2020" study, long-distance European rail traffic will increase by about 20 percent by 2020, and passenger numbers will exceed 1.36 billion.
Ensuring that this amount of mobility will be available in future is one of the major challenges of our times. An efficient long-distance railway infrastructure forms the basis for environmentally compatible mobility without borders, as well as for the further economic development of regions and countries.
Against this background, Siemens will demonstrate how safe, interoperable European rail traffic "without borders" can actually be achieved in Gallery 2, B3 at the 11th UIC (Union internationale des chemins de fer) ERTMS World Conference in Istanbul, which is to be held on April 1–4, 2014.
ETCS increases line capacity and ensures continuous rail traffic throughout Europe.
Train protection systems ensure safe rail transportation of passengers and goods. There are currently 14 different train protection systems in use in Europe, which are mutually incompatible. The European Union Directive issued in 1996 to resolve this compatibility problem obligated European train and network operators to equip their trains and lines with the European Train Control System (ETCS). ETCS is a modular system with standardized functions and interfaces that are available in a number of application levels. With ETCS Level 1, the signal aspects are transmitted to the vehicles with the aid of beacons called eurobalises. Level 2, however, uses the mobile radio standard GSM-R to transmit this information from a route control center to the vehicle. With this technology, information is continuously exchanged, independently of fixed signals. This facilitates short intervals between trains and considerably increases the route capacity and safety at speeds up to 350 km/h. At the World Conference, an ETCS emulator "ETCS live" will demonstrate the results of optimized acceleration, driving and braking operations in respect of punctuality and energy efficiency. Visitors will be able see an ATO (Automatic Train Operation) system: The demonstration is based on genuine track data, and every action of a real train driver has to be duplicated to move the train along the realistic track. The ATO beats the energy consumption achieved by even experienced train drivers by five to ten percent. This means that ETCS in combination with this component can use small reserves in the timetables to reap substantial energy savings. The Automation Train Operation system takes over the driving the train on the route and stops it with precision at the platforms. With the aid of the stored route profile, the system calculates how strongly the train has to accelerate and to brake before curves in order to arrive punctually at the next station – and, in doing so, consume as little energy as possible.
The Driver Advisory System optimizes train control and reduces energy consumption
In response to increasing energy and operating costs and in order to reduce CO2 emissions, more and more railway operators are finding it necessary to demand energy-saving, low-wear driving skills from their drivers. As train drivers are often deployed flexibly, they are not always capable of finding the ideal speed profile on every route. The DAS (Driver Advisory System) can now give them suggestions for improving train control. The combination of route data, such as maximum permissible speeds and distance between stations, as well as timetable information enable an optimized speed profile to be calculated and is then recommended to the train driver visually in real-time. The aim is to have drivers follow the optimum speed profile on every route in order to save energy and reduce wear. Whereas DAS still allows the train driver to control the train himself, the ATO system takes over optimized driving of the train until the train stops at the next platform.
Predictive maintenance by means of Condition Monitoring
Rail transportation systems have to run smoothly without interrupting the flows of passengers and goods. Competent and innovative servicing is required to meet the ever increasing availability demands of these systems. In this connection, Siemens uses "Condition Monitoring" to plan maintenance activities efficiently and minimize disruptions to operations. The system data is collected by long-distance transmission and flows directly into everyday maintenance activities. This enables impending damage to be detected at an early stage. Diagnostic data describes the current condition of the systems, assesses trends and provides a catalog of measures to rectify defects.

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...

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...
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...
