2 Shanghai Maglev Transrapid Project The Line Project data Line 30 km double-track guideway Stations 2 Journey time Headway Operational speed Passengers 7.5 minutes 10 minutes max. 430 kph 15,000 per day Operation per day max. 18 hours per day 2

3 Transrapid System Characteristics Comfortable Safe Eco-friendly Economical Short trip time due to high acceleration and high velocity Punctual due to high availability Barrier-free access to the vehicles Fully automated operation Protected against derailing due to wrap-around vehicle design Silent due to contactfree technology and flat surfaces Energy-efficient due to better aerodynamics Less vibration due to magnetic levitation Easy integration into existing landscape Less maintenance due to contact-free technology Fewer tunnels and bridges due to high gradeability Propulsion power adaptable to the line topography 3

4 Shanghai Maglev Transrapid Project Experience Comfortable Short trip time due to high acceleration and high velocity Punctual due to high availability Barrier-free access to the vehicles Revenue service Demonstration run Maximum speed v max = 430 km/h v max = 501 km/h Maximum acceleration a max = 1.0 m/s² a max = 1.0 m/s² Average speed v aver = 240 km/h v aver = 296 km/h Average acceleration a aver = 0.62 m/s² a aver = 0.62 m/s² Journey time t = 7.5 min t = 6.7 min Punctuality P = 99.95% (5 of rides > 5 min delay) Barrier-free access (fig. top right) 4

5 Shanghai Maglev Transrapid Project Experience Safe Fully automated operation Protected against derailing due to wrap-around vehicle design First driverless high-speed transportation system in operation High-precision stopping of the vehicle (± 10 cm) Wrap-around vehicle design (fig. top right) 5

6 Shanghai Maglev Transrapid Project Experience Eco-friendly Silent due to contactfree technology and flat surfaces Energy-efficient due to better aerodynamics Less vibration due to magnetic levitation Easy integration into existing landscape Silent due to magnetic levitation instead of wheels air gap instead of abrasion electronics instead of mechanics Energy-efficient due to low aerodynamic resistance (no bogies, no pantographs) Low CO 2 emission Low electromagnetic flux density Low vibration due to low mechanical loads 6

7 Shanghai Maglev Transrapid Project Experience Economical Less maintenance due to contact-free technology Fewer tunnels and bridges due to high gradeability Propulsion power adaptable to the line topography No abrasion on track Few maintenance-intensive mechanical parts (no wheel sets, no gear) Gradeability up to 10% (relevant for extension line tunnel length) Propulsion power blocks in low power version for shunting and high power version for high-speed 7

8 Transrapid System Development Source: ThyssenKrupp Comfortable Short trip time due to high acceleration and high velocity Punctual due to high availability Barrier-free access to the vehicles Shorter headway due to switchable propulsion and operation control segments at the stations (t min = 5 min) Wide pressure-tight vehicle doors (1.2 m) allow high-speed traffic and fast, easy passenger exchange (fig. top right). The new room concept in the vehicle is generously designed. 8

9 Transrapid System Development Source: Fogtec Safe Fully automated operation Protected against derailing due to wrap-around vehicle design Operation control structure allows large-sized Transrapid networks. Platform screen doors for unattended operation (fig. top left and middle) Water fog system for fire-fighting in the vehicle (fig. top right) increase system safety. 9

10 Transrapid System Development Eco-friendly Silent due to contactfree technology and flat surfaces Energy-efficient due to better aerodynamics Less vibration due to magnetic levitation Easy integration into existing landscape Reduced aerodynamic resistance due to inductive auxiliary power supply system (no pantographs necessary) Aerodynamic and aeroacoustic optimization of the vehicle reduce the acoustic emission and the acoustic noise inside the vehicle Feedback of braking energy by active front-end converters 10

11 Transrapid System Development Source: Max Bögl Economical Less maintenance due to contact-free technology Fewer tunnels and bridges due to high gradeability Propulsion power adaptable to the line topography New concrete guideway beams including the pre-assembled system components, e.g. stator packs, guidance rail (fig. top left) Trackside cables integrated in the guideway beam (symmetric cable laying, air cooling, easy troubleshooting, fig. top middle) Construction kit with standard industrial components (e.g. standard converters, switchgears, industrial PC) Low-weight switch stations (6 instead of 30 t) along the track (fig. top right) 11

12 Transrapid Innovation Summary and Outlook Optimal Application High speed between 300 and 500 km/h, station distances from 30 km Transrapid is suited for long-distance connections from city to city up to 600 km (time and eco advantages compared with planes) and connection of traffic nodes in regional areas, e.g. high-quality airport connector to the city centre (Shanghai, Munich) Advantages of Transrapid Technology Comfortable and fast High level of availability and punctuality (Shanghai: 99.95%) Safe Eco-friendly compared with other carriers Innovative future technologies with high efficiency potential Highly economical due to low maintenance effort 12
