13. << 13 Classic pre measuring tools –Tamping machine –Using physical wire

14. << 14 Classic pre measuring tools –EM Sat Laser Alignment Alignment Method is prescribed for lines for lines with a design speed > 160 km/h

15. << 15 Classic pre measuring tools –Geodetic trolley Instrument outside of the track Free station setup ~ 150 m in both directions Productivity can be increased by using two instruments

24. << 24 Theory ↔ Practice by … Watch the system from a point of view of practical application!

25. << 25  Assigned Manpower!  Train blockings as long as you order  No spatial problems along the track  Purpose of work: just finalizing, don‘t think about the accuracy  Enough time for the project What is “standard”?  Money is of no importance!

26. << 26 Is this REAL LIFE??? NOT OURS !

27. << 27 Description of the workflow  Before the measurement – data management –Basic data needed  Track axis  Gradient  Fixpoints along the track including reference values  Digital or Analogue

28. << 28 Description of the workflow  Before the measurement – data management –Case 1: Workflow by using digital data  Convert the axis data into the data type needed by using the software GEDOoffice  Fixpoints in a csv-file (kind of Excel respectively ASCII data type) –That’s it!

29. << 29 Description of the workflow  Before the measurement – data management –Case 2: Workflow by using analog data (track marking plan)  Manual input of numerical data belonging to the relaying track  Reference values of fixpoints  Camber  Data of superelevation  Gradient data  Input by using the software VorsysCE Duration of data input: Analogue: 1 hour / 1 kilometer (= 0.6 miles) Digital: 5 minutes / 100 kilometer and more → NO track-blockings before the measurement!

30. << 30 Description of the workflow  During the measurement –Calibration of the trolley –Parameters of the trolley –Using the flexibility of the system –Starting the software VorsysCE - Starting a project –Starting the radio link

37. << 37 Alternatives of using the system  Other possibilities to fix the track geometry  Documentation of the track set after reaching the target position (2nd stabilisation) –Comparison of actual and theoretical track set –Marking out geometry main points –Proof of the gage

38. << 38 Future prospects…  Including GPS-Data  Documentation of the actual track set in plane and height without any axis data  Track monitoring

39. << 39 THIS is our “standard” !  Manpower only as much as needed!  Avoidance of train-blockings  No extra space needed…only the gage!  Data interpretation directly on site  Accurate and fast Conclusion  Optimal cost-benefit-factor     
