2 I. HSR, AN INTEGRATED SYSTEM I

3 Different transportation modes Pedestrian HS Train single unit system multicomponent complex system Different performance level I.1

4 ELECTRIFICATION SIGNALING TRAIN PERMANENT WAY INFRASTRUCTURE I.2

5 I.2

6 Different transportation modes Single, closed, system Component by component Different strategies and results Purchase strategy Suppliers selection process Industrial development strategy System management options I.3

7 The great integration level of the railroad system Different level of integration / different performance level I.4

8 II. JOURNEY TIME AS THE MAIN GOAL II

9 Transportation systems main target minimum travel time Time versus speed (maximum, average, minimum) Other modes limits to speed I. 1 6 Lower level of integration - Safety - Economy - Environmental issues II.1

10 I. Km/h COMPARISON WITH OTHER MODELS Maximum speed test Maximum operating speed II.2

11 Journey time is the main driver of the HSR system Capacity improvement is also at the origin of this technology (Japan, Paris-Lyon) Main components involved (infrastructure, rolling stock) Different time scale to be considered - Long term - Mid term - Short term Efficient management - Infrastructure - Permanent way - Electrification - Safety /signaling /communications - Rolling stock II.3

12 III. THE WAY, THE ALIGNMENT, THE INFRASTRUCTURE III

13 llllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll III.1

14 Advantages of a self guided system - Safety - Comfort level - Centralized traffic control Reliability, cost effectiveness, high speed Comparison with other modes - Road - Air - Shipping Self guidance as key factor for journey time performance III.2

15 Plan alignment and long profile play a main role in the speed / journey time definition Main parameter involved on the speed definition - Curve radius - Transversal acceleration - Cant - Slope (value and length) External factors to be considered - Environmental - Row availability - Costs Corridor study - Straight alignment - Intermediate cities - Final decision options multicriteria analysis III.3

18 Existing line curvature diagram III.5

19 Main factors to take into account - Territory structure - Environmental condition - Orography - Urban areas - Hydrological and geotechnical conditions Sequential development - Corridor analysis functionality/intermodality/connectivity - Route selection and predesign journey time/performance cost analysis - Detailed design detailed alignment geometry III.7

20 International standards Interpretation Limiting values Maximum speed Complex parameters Tilting trains III.8

21 IV. THE ROLLING STOCK IV

22 Main role in journey time Technology under continuous evolution Compatibility / interoperability Key factors - Adherence - Power - Traction effort - Mass IV.1

23 TRAIN POWER DIAGRAM 20 IV.2

24 Technology trends - Acceleration capacity - Braking process - Tilting bodies Associated costs - Purchasing - Maintenance - Operational - Energy efficiency IV.3
