“Complete mobility” – the comprehensive range of services from Siemens for the multimodal linking of rail with other means of transportation


Berlin, Germany, The slogan at this year’s InnoTrans is “The future of mobility” and this future is posing great challenges to operators and infrastructure planners. For climate change, growing urbanization, population growth in the emerging markets, and globalization will lead in future to increasing demands for mobility and transportation all over the world. With its “Complete Mobility” concept, the Siemens Mobility Division offers comprehensive, sustainable solutions to meet these challenges. “Complete mobility” means the intelligent networking of traffic flows on rail, road and in the air. In Hall 4.2 and in the outdoor exhibits, Siemens Mobility will show how multimodal transportation networks can become reality. The main exhibits at this year’s show are the new Velaro D high-speed trainset for eco-friendly links between cities, the new Vectron locomotive generation for cross-border European rail traffic, and an energy-optimized train control system for more economical operation on mass transit and mainline routes. Using the example of its Airport Rail Links, Siemens will demonstrate the efficiency attainable from the increased networking of passenger and freight transport as well as air travel. It will also show the potentials of multimodal traffic management which can improve the environmental compatibility and energy efficiency of transportation systems. Personal electrical mobility will also become a major factor in future: Siemens will show ways and opportunities for integrating electric cars into the multimodal transportation infrastructure. Service and “Complete mobility” consulting embrace all the technological fields and are important elements in the corporate portfolio.

Maintaining mobility will become one of the major tasks of modern societies in future. For example, according to the EU Commission, the transportation sector generates ten percent of the wealth in the European Union, as measured by gross domestic product, and it provides over ten million jobs. The constantly rising demand for mobility is placing a great burden on our transportation systems. In the EU, 44 percent of goods are transported by road, compared to only ten percent by rail. When it comes to passenger transportation, the dominance of the road is even more pronounced at 81 percent, while rail has only 6 and air 8 percent. The infrastructure is obviously overloaded, resulting in a fall in economic efficiency and an increase in fuel consumption and air pollution. Shifting freight and passenger traffic from the road to more environmentally compatible carriers therefore lies at the heart of every sustainable transportation policy. Transportation planners and operators are realizing more and more that it is becoming ever more important to offer their end customers an unbroken chain of mobility. Tomorrow’s mobility requirements can only be met if the individual carriers are optimally networked and work together to provide trouble-free interchanges from one to another. Rail has a leading role to play in this because it is the most environmentally sustainable, most energy efficient and most effective means of transportation.

The Velaro – for an eco-friendly, high-speed link between urban centers

Demands on rail operators are growing: a network of fast, cross-border links between conurbations is the environmentally sustainable, future-oriented alternative to plane and the car. To this end, Siemens Mobility is offering its Velaro platform, a trainset that is already providing reliable service on Spanish, Chinese and Russian tracks. It has combined the insights gained from the fleets in operation and customer requirements in a further step in its development. The most visible improvements are the fairings on the roof-mounted equipment, bogies and inter-car gangways. The spoilers, front ends and end modules have also been streamlined to further optimize the aerodynamics. A high roof starting from the center of the end car reduces not only the so-called “sonic boom” when entering a tunnel but also the running resistance and exterior noise. The intelligent energy manager in the Velaro D ensures that the train systems run at maximum efficiency. Together, these improvements further reduce the equivalent CO2 emissions of the Velaro D, which are only one tenth of airplane emissions per passenger kilometer. The Velaro D is a train based on the multiple-unit concept in which the traction equipment and all the technical modules are distributed under floor over the entire length of the train. For any given train length, this increases the available space by twenty percent in comparison to other vehicle designs. The interior is modular and adaptable: additional baggage racks or tables can be fitted as and when required – even overnight. This increases seating capacity and passenger comfort and gives the operator optimum adaptability to changing operational requirements. Deutsche Bahn has came out in favor of the Velaro by ordering 15 eight-car trains from Siemens Mobility in December 2008. Proven reliability, increased energy efficiency and greater ease of maintenance make the Velaro D the current standard for high-speed trains.

Inspiro – the new platform for metros

A fast and safe public passenger transportation system is a crucial factor in the quality of life and competitiveness in cities and regions. Sustainable, optimally channeled mobility will thus be a key issue of the 21st century. The challenge is to optimize traffic flows in conurbations while at the same time reducing total CO2 emissions. Metros are an environmentally sustainable means of transportation. Apart from increased demands for passenger comfort, the main consideration is maximizing system capacity under optimal commercial conditions. The new Inspiro metro platform is oriented toward these criteria. Siemens uses it as an example to show how the needs of the operator, passenger and environment can be reconciled. A special train concept based on self-contained units enables any configuration from a three to an eight-car train to be formed with variable degrees of motorization. Boarding and exiting times have been greatly reduced by maximizing door widths and load detection systems. The design has eliminated all equipment from the interior space, not only making it available for passengers but also offering maximum comfort. Consistent lightweight construction, optional use of the Syntegra drive system, driver assistance systems and even driverless operation ensure utmost energy efficiency and system capacity. The vehicles meet the latest European fire protection and crash requirements of CEN/TS45545 and prEN15227. A demand-actuated maintenance concept increases operational availability and reduces maintenance costs. The new Metro was designed by one of the most prestigious design agencies.

The Vectron – the new generation of locomotives for European rail traffic

Efficient, multimodal rail transportation is an important success factor not only for individual companies but also for entire national economies and global markets. Fast, economical rail links between major international ports, inland freight transshipment centers, metropolitan regions, and producers and customers all across Europe are, for example, important prerequisites for shifting as much goods traffic as possible from road to rail and thus reducing road traffic CO2 emissions. With the new Vectron locomotive, Siemens Mobility is offering a product for passenger and freight transport that has been designed to meet the increasingly changeable requirements and transport tasks in Europe. The development focused not only on investment protection, environmental compatibility and fungibility, but also on ease of retrofitting and conversion. The Vectron is also attractive to customers who want to buy smaller numbers of units. The locomotives are designed for a standard maximum speed of 160 km/h. A Vectron with an appropriate preliminary equipment package can be upgraded to a 200 km/h version without necessitating any major modifications. For example, there is no need to change the bogies. The various versions, i.e. strictly AC or DC and versatile multi-system types, enable operation on four different line voltages and in a range of performance classes. A special feature of the Siemens vehicle concept is the internal deformation zone, the front end. It has a detachable connection to car body, which makes it easy to replace in the event of an accident. The machine compartment layout provides three rack positions for installing train protection cabinets. The train protection cabinets are fully modularized to facilitate easy conversion and retrofitting. The underfloor area and the bogie have been prepared for mounting the required antennae and speed encoders. The machine compartment layout with a central aisle provides a straight escape route and optimal use of space. Good accessibility in the machine compartment also makes maintenance easy.

Desiro ML – the modular vehicle platform for regional rail service

At Innotrans 2010, Siemens will be exhibiting another version of the Desiro ML which has been designed for Belgium State Railways (SNCB). The longer train length of almost 80 meters provides a seating capacity of 280. These trains will be delivered to the SNCB starting in 2010 as part of an order calling for 305 three-car electric multiple units.The diesel-generator set newly developed for the diesel-electric version of the Desiro ML will also be on show. It already meets the latest stage 3b emission requirements. With its newly designed diesel-electric propulsion system, the Desiro ML DMU offers a truly innovative and especially environmentally friendly solution. It can achieve energy savings of up to thirty percent in comparison to conventional diesel-mechanical or diesel-electric traction systems. The diesel-electric propulsion system also requires less time and money for maintenance. The Desiro ML is already proving very successful both at home and abroad. Over 600 orders have been received, either confirmed or notified through master agreements. As well as the orders from Germany and Belgium, vehicles from the Desiro ML platform will soon also be running in Austria, Russia and China.

Siemens Rail Services for high availability rail operations

Rail-based transportation systems have to run without a hitch so as not to interrupt the flows of passengers and goods. Competent and innovative servicing is required to meet the ever increasing availability demands of these systems. Siemens Mobility Rail Services offer comprehensive services throughout the entire product life cycle. These start with tests and commissioning in the Siemens-own Test and Validation Center in Wegberg-Wildenrath, continue with preventive and corrective maintenance and comprehensive spare part management through to repairs and refurbishments to lengthen service lives. In this connection, Siemens Mobility uses “Condition Monitoring” to plan maintenance activities efficiently and minimize interruptions to operations. The system data is collected by long-distance transmission, and flows directly into everyday maintenance activities. Siemens Mobility is also widening its range of services for locomotives with its new, modular Railcover service concept. The newly established Rail Support Center monitors connected systems by long-distance data radio transmission, and coordinates the mobile service technicians and workshops in the event of a vehicle malfunction. Express logistics ensure fast, trouble-free supplies of spare parts.

Airport Rail-Link – rail transportation and logistics combined for an efficient airport link

The transit to the air carrier is a particular challenge for an intermodal transportation network. Airports are generally located outside cities and conurbations, but people and goods should still be able to reach them quickly and without burdening resources. A metro line from the city center is therefore an extremely suitable form of transportation. The Siemens Airport Rail Link combines rail transportation and logistics solutions. For example, the Sibag Train baggage handling system from Siemens Mobility is a very convenient service for passengers. Passengers can check in their bags and collect their boarding cards at subway stations in the city center before traveling to the airport in the airport express. On arrival, they can go straight to the security check and the departure gate. Their checked baggage arrives separately at the airport. There it is fed into the baggage handling system, runs through the automatic security screening, and is loaded onto the airplanes flying to the particular destination airports. The train’s baggage car is equipped with a conveyor system to take the bags from the station. A feeding system on the station platform loads the bags into a container, which is automatically loaded through a door into the car. When a train arrives at a metro station, the container system is waiting exactly opposite the loading door. Loading is extremely quick, so passengers boarding the train do not have to wait. Sibag Train controls the entire process precisely and completely automatically. This Siemens solution is in use in airport rail links in Bangkok and Delhi among other places.

Electric mobility for private transportation complements a multimodal urban infrastructure

Road traffic currently contributes to nearly 15 percent of the greenhouse gas emissions. However, the dramatic increases in traffic volumes which are expected in the coming decades, especially in the threshold countries, are focusing attention more closely on the car. The electric mobility issue is thus also relevant to private car use. Germany intends to bring one million electric cars onto the road by 2020. The USA is aiming to reach this target by 2015, and China is currently investing two billion euros in pilot projects with thousands of electric vehicles. Especially in towns, the challenge is to organize the various transportation systems and coordinate them with one another. There are a number of conceivable ways of linking the electric mobility of the road and the rail: namely, car-sharing schemes at stations, fleets of electric city taxis, park & charge spaces in multi-storey car parks, and local delivery transport in cities. Siemens is a pioneer and general supplier of electric mobility solutions, and the only company in the world to cover the complete electric mobility process chain. This runs from intelligent energy and transportation infrastructure solutions through recharging technologies and high-performance IT systems to researching the drive technology required. Siemens will be exhibiting amongst others the Sitraffic Epos electric charging station at InnoTrans. This electric charging station is more than just a “gas station” for electric vehicles, it is a complete unit with an information terminal. With this electric charging station, Siemens intends to make a big contribution to the future use of electric vehicles. The intelligent Siemens electric charging station is clearly very different from previous solutions in test and pilot applications. Sitraffic Epos has a modular structure, and can be configured either as a single electric charging unit or as a station with up to ten satellite connections. It can be used wherever the recharging of a number of electric vehicles is practical, for example in multi-storey car parks at railway stations.

Efficient electrification solutions for smooth rail traffic

Energy storage systems store the energy generated during braking and can then feed it back into the system when required. This substantially reduces power consumption and stabilizes the line voltage. Siemens supplies the storage systems required for each electrification system: Sitras SES for stationary use; Sitras MES for use on board trains; and Sitras HES, which has an additional traction battery that makes mobile use possible even where there is no overhead contact line. All versions contain the new Sitras ESM 125 core module. It employs double-layer capacitors, which can be converted to higher voltage units by connecting several modules in series. This makes the storage modules even more compact and efficient. And with adapted cooling they are even suitable for use under extreme climatic conditions, such as those encountered in Arab countries.An efficient rail electrification system requires precise planning. The Sitras Sidytrac simulation software can handle this task. It generates an exact network calculation, including train operation simulation, on the basis of track and vehicle data, the timetable and the electric network data. It is immaterial if the analysis is intended to design a new system or to find potential for improving an existing system. Saving energy and reducing life cycle costs are beneficial effects – both ecologically and economically.

The Sitras SFC plus multilevel traction converter is another element in a “green” traction power supply which has a different frequency to that of the national grid. A number of semiconductor modules and capacitors connected in series can build up and control the desired voltage from small taps. The Sitras SFC plus has such a high output voltage and number of voltage levels that losses are up to 25 percent lower than in other converter systems. The new compact modules also require 20 percent less space and are considerably quieter than typical models on the market.

“Green” safety for rail automation

Trains and tracks are protected by both interlockings and on-board equipment. These systems currently work closely together, primarily to ensure safety and smooth rail operations. Innovative technologies are also improving the commercial efficiency of rail operators to an ever greater extent. Online algorithms implemented in the on-board computers reduce not only power consumption by at least 25% but also vehicle wear. At the same time, line capacity – for example on metros – can be increased by up to 50% and punctuality improved. In order to achieve this, an optimal speed command is calculated from the current position and timetable position and sent to the vehicle, including complex parameters. This eliminates unnecessary accelerations, which consume energy and impose strain on vehicles.

Siemens will be presenting this new type of function for automatic train operation (ATO) live at InnoTrans. Visitors will be able to compete against an ATO system at an ETCS simulator. The demonstration is based on genuine track data, and every action of a real train driver has to be performed to move the train along the realistic line. The ATO beats even the best-trained drivers by five to ten percent. This means that minor reserves in timetables can be used for substantial energy savings. For the first time, the ETCS simulator will also be demonstrating at InnoTrans how timetabling interacts with online optimization by means of dispatching control using Siemens’ Falko system. On the basis of original line data, the online connection of Falko components to ETCS will realistically visualize interaction between train dispatching and train control in both 3D and real time.

Siemens is also developing state-of-the-art technologies even further. Standby systems for rail automation components along the track optimize energy consumption – for example, by using solar energy to generate power for signaling systems and their radio control. This enables great savings to be achieved in cabling components, and investment costs can be reduced by up to one third. Signaling systems consisting of such outdoor equipment also reduce the life-cycle costs of complete trackside facilities.

Trainguard 200 RBC – a central device for ETCS Levels 1 and 2

Siemens offers an ETCS solution for Levels 1 and 2 in a central device specifically for long-distance traffic. Trainguard 200 RBC (radio block center) transmits all information required on Level 2 for a safe journey via GSM-R radio technology. As it also controls ETCS Level 1 balises, the system can be integrated into existing infrastructures without extensive adaptation and can take over the tasks of a central lineside electronic unit (LEU). Mixed operation with different ETCS levels and national train protection systems is supported. There are also additional advantages gained by using standardized interfaces for different interlocking types. Trainguard 200 RBC is based on Siemens’ Simis platforms and can therefore easily be integrated into existing Simis interlockings. Using the same hardware platform is advantageous for maintenance and servicing, reducing life-cycle costs.

Control systems for railways of the future

In our technologically focused society, more and more information is being made available in increasingly shorter periods of time. The ability to capture, evaluate and process this data is therefore of key significance. This is particularly the case for safety-related areas and, very specifically, for railway control centers. The breakneck speed in technical progress in information, communication and interaction technology does not stop at classic control systems. At InnoTrans, Siemens will be making design-oriented approaches for innovative railway control systems of the future a hands-on experience.

The Siemens solutions for the effective processing of versatile information are revolutionizing work routines: planning and control of train fleet and staff deployment, monitoring of train running times and the infrastructure, handling of potential bottlenecks, planning of non-scheduled trains and organization of diversions – the daily tasks of the control center are perceptibly optimized by the re-organized interaction of functions and roles. A rapid grasp of things by staff, efficient system interfaces and operational sequences, and ergonomic workplaces make the new generation of control centers a major value-added factor. In addition to workplace design, a prudent balance between functional, ergonomic and economic aspects is imperative. The challenge for control systems to separate the essential from the inessential and thus to be able to control the flood of incoming information is at the focus of new developments. From innovative technologies through economic impact to possible consequences in work organization, Siemens will be presenting its vision of railway control systems of the future for discussion, both vividly and hands-on, in an interactive simulation world – the “Operations Control Interaction Lab”.
