Title: MULTISYSTEM HIGH-POWER LOCOMOTIVE – STATE OF THE ART AND EXEMPLARY DESIGN
Andreas Steimel and Roman Bartelt
ABSTRACT: The electrification of European mainline railways started very early in the 20thcentury, using different DC and AC technologies. But it was only after the onset of thecommon European Market, that the need for traction material arose which could beoperated inthe four remaining supply systems freely. While withthe classic traction with series-wound commutator motors technologies special (and uneconomic) constructions were needed, the three-phase drive technology with Voltage Source Inverters and Four-Quadrant line-side converters employing self-commutating devices (GTO) enabled by its modularityrather simple and economic solutions. The introduction of 6.5-kVIGBTs allowed further standardization and increased performance and thus the economical break-through of four-system traction material.
Based on these new possibilities, the design and optimization of multisystem locomotives has to be improved (very much) to meet all requirements of the different railway supply systems. Considering the locomotive requirements and the limits of all preferred components, in cooperation with CRRC ZELC a complete software-based optimization process is implemented. Starting with an initial dimensioning based on decades of experience, the detailed calculation of every single component is developed analytically and numerically. Additionally, the complete software process includes the detailed simulation with the softwareframework VIAvento which has been designed especially for the simulation of power-electronic systems like modern converter-fed locomotives. Selected simulation results will be shown in the presentation.

Title: APPLICATION OF TRAIN DATA RESOURCES IN OPERATION AND MAINTENANCE
ABSTRACT：Up to the end of 2015, China had completed the establishment of 4 vertical and 4 horizontal high-speed railway network in advance. The total operating mileage of high-speed railway reaches 22,000 km, and the amount of operating high-speed EMUs exceeds 2642, significantly improving people’s travel mode and experience.
However, since the increasing of operating train amount, on one hand, the operation and maintenance cost increases obviously due to the lacking of high-efficient operation and maintenance mode; on the other hand, a large number of data resources generated during train operation and maintenance have not been used effectively.In order to change the present situation, intelligent learning methods are adopted to mine “knowledge information” in data resources of operation and maintenance of EMU, so as to establish assessment model for service performances of main equipment such as traction motor, bearing. The model predicts the performances on the basis of current operating conditions and assesses the current performance and state of such equipment in accordance with prediction results, test results and historical data, so as to optimize operation and maintenance mechanism as well as inventory management of spare parts.On the basis of establishing assessment model for service performances of equipment, by means of abundant data resources of operation and maintenance, service functions such as integral service of predictive equipment maintenance and accessories as well as virtual and visual remote guidance are gradually realized, and the operation and maintenance mode of EMU is improved, so as to drive the completion of transformation from a large amount of “data” to “knowledge” and then to “value” for train operation and maintenance.

Title: APPLICATION OF BIM TO RAILWAY MAINTENANCE PRACTICE
ABSTRACT：Maintenance of railway systems, such as track, signal, power supply, and vehicle systems can increase safety and reliability of railway network to provide best service for their passengers and customers. However, the absence of sufficient information required in the maintenance activity can result in failures of railway systems. Building Information Modelling (BIM) has become a powerful and useful technology in the transformation towards digital maintenance work by producing Level of Graphical Detail (LOD) of the 3D and 4D simulation models. It can be applied not only for track renewal, but can also be used in maintenance work of signal, power supply, and vehicle systems.This keynote addresses what BIM is, why it is needed, BIM in practice, challengesin creating a 4D schedule for track renewal maintenance work, and two short video clips are used to demonstrate the application of BIM to construction and maintenance practice simulations.

Title: TRAIN CONTROL AND INFORMATION SERVICE NETWORK BASED ON ISOCHRONOUS DETERMINISTIC BROAD NETWORK
ABSTRACT：For many years, to deliver train control command data, bus-based train communication networks (TCNs) have been widely applied. The reliability and security of these networks have been tested strictly. However, the network capacity of such networks are very limited, which can no longer meet the demand of applications, i.e., CCTV, audio/video and IoT. To satisfy the capacity needs of those data-intensive applications, a new train control and information service network (TCSN) has been developed recently. Besides higher bandwidth, TCSN is more flexible and more compatible compare to bus-based TCNs. On the other hand, the reliability and security of TCSN should be studied thoughtfully, due to their de-centralization and openness.
In this report, a brief introduction of TCSN is proposed, including its development history, architecture, core technologies, system and applications. The report also highlights the advantages and convenience that TCSN will bring to modern trains. Finally, the future of TCSN is brought. We believe that with TCSN, train will be more and more intelligent and passengers will have safer, more convenient and comfortable travel experience in the near future.

Title: INTELLIGENT DRIVER ADVISORY SPEED SYSTEMS FOR MORE PUNCTUAL AND ENERGY SAVING TRAIN OPERATION
Ingo A. Hansen
Delft University of Technology
ABSTRACT：Conventional driver advisory systems are bound to the communication of scheduled local speed advices for regular train operation while neglecting the impact of actual train delays and traffic density in railway networks. Intelligent driver advisory systems make use of real-time traffic information generated by signalling and safety systems of the track infrastructure which are communicated via digital radio to a central traffic control unit. A central traffic control unit then computes and transmits globally optimal speed profiles in real-time to the on-board units of the trains that generate conflict-free and energy-optimal speed advices at local level. The computation and communication of accurate advisory speed changes based on optimal speed profiles at open track sections and in interlocking areas assure conflict-free train operations, can reduce train delays and save energy.

Title: HIGH EFFICIENCY WIRELESS CHARGING OF ELECTRIC VEHICLES
ABSTRACT：Wireless power transfer (WPT) technology offers significant improvement in convenience and electric safety for electric vehicle (EV) charging. Our research aims at novel designs that considerably reduce size and cost while increasing the coupling coefficient and improving the misalignment capability. We will first introduce the basics of WPT, followed by discussion of a double-sided LCC topology which further enhances the system efficiency. Experiments show that tens of kilowatts of power transfer can be achieved over 200mm distance with an efficiency of 97% (DC-DC), and a misalignment tolerance of up to 300mm. We will then discuss the capacitive wireless power transfer (CPT) for EV charging applications. It has been an established myth that good efficiency and stability of control was only possible at low power levels (in the tens of watts) and with low transfer distances (in the millimeter range) for CPT. We have shown that it is possible to achieve excellent efficiencies at the power level and distance applicable to EV charging, breaking the established myth, enabling a paradigm change on EV charging, and making low cost wireless power transfer possible A double-sided LCLC topology was proposed. A 2.4kW CPT system was designed with four 610mm × 610mm aluminum plates at a distance of 150mm. The experimental prototype reached a DC-DC efficiency of 92% at 2.4kW output power. The CPT system provides a lower cost and better misalignment capability then inductive wireless power transfer systems.

Title: OPTIMIZATION AND BIG DATA ANALYSIS IN RAILWAY OPERATIONS MANAGEMENT
ABSTRACT：Data analysis to improve the quality of operations: application to Crossrail. The presentation will focus on the results of a real-world application of data analysis to to improve the quality of operations, which was carried out in 2016 byTRENOlab for MTR Crossrail in London. A combination of historical train movement and ticketing data was used to identify the critical elements in the operations of the London -Shenfield line and to drive a set of timetable tweaks, which where first validated using stochastic simulation and then applied to the real timetable, obtaining a significant improvement of the quality of operations.
Simulation of railway operations: strengths, weaknesses and unexploited potentials. The stochastic simulation of railway operations is the ideal companion of railway planners during most stages of planning since it allows evaluating the impact of new or improved infrastructure, timetables and rolling stock before constructing them or even before planning them in detail. Although powerful simulation tools have been on the market for the last 10-15 years, and have been widely used in several Countries, a number of weaknesses limit their usability and the reliability of their results, in particular under delayed conditions. The presentation will cover the strengths and the weaknesses of the approach, and identify ways to broaden its applicability.

Title: FSO-BASED COMMUNICATIONS TECHNOLOGIES FOR HIGH-SPEED RAILWAY SYSTEMS
ABSTRACT：High-speed trains (HSTs), which travel at speeds of 300 km/h or faster, have played an increasingly significant role in recent public transportation. For example, the number of HST passengers in China has increased from 128 million in 2008 to 672 million in 2013, representing an annual growth of approximately 39% during that period. Because of the increasing number of passengers and bandwidth-hungry online streaming services, such as Youku, the demand for high-speed Internet access on HSTs is also on the rise. Several technologies are being considered for HST communications but they cannot provide high data rates because of interference, bandwidth limitations, and the inherent limited data rates of radio-frequency technology. Free-space optical (FSO) communication is an alternative approach to them. This is a line-of-sight technology that uses modulated light to transfer data. Its benefits over radio-frequency technologies include immunity to electromagnetic interference and high security owing its use of directed light, and the use of an unregulated range of the spectrum. FSO technology can use multiple parallel beams to provide unprecedentedly high data rates. For instance, an FSO communications system that provides a date rate of 1.28 Tbps using 32 parallel channels, each providing 40 Gbps, with a range of 210 m between two stationary stations has been demonstrated. FSO technology has attracted significant attention for high-speed railway communications since it is expected that FSO can provide data rates in the range of Gigabits per second for HSTs. Therefore, it can be considered as a next generation communications technology for high-speed trains and railway systems. This talk reports our recent progress in collaboration with CRRC Zhuzhou Institute Co. Ltd. He will reveal two advances: Free-space OptiCs Utilization in high-Speed trains (called FOCUS for short) as a new architecture and a RotAting TranscEiver scheme (RATE) to mitigate the impact of handover processes with steerable FSO transceivers in a ground-to-train communications system.
