6 Data Preparation and Simulation 2000: ÖBB starts using BEST (Betriebs- und Stellwerkssimulation) as a simulation training tool for electronic interlockings2001: ÖBB starts planning of electronic interlockings with the BEST editor2003: Additional functions are implemented in the editor2005: ÖBB Planning centre for electronic interlockings is fully established and uses the BEST editor and the BEST simulator not only for planning, but also for the verification of new interlockings and functionality with the users

8 Data Preparation and ETCS (1) Data Preparation ToolIDAFFSignallingIndustryDuring the process of planning ETCS Level 1 Vienna – Salzburg and discussing the IDAFF, ÖBB mentioned, that most of the DATA needed for ETCS is included in IDAFFThe amount of DATA for the Vienna - Salzburg Project seems to be so extensive, that an engineer alone cannot handle it (an experience from the smaller Vienna - Budapest project)
9 Data Preparation and ETCS (2) There are stations with very complex topology Simulation of breaking curves for checking the position and data of balises Simulation of breaking curves for checking the necessity of infill loops and balisesElectronic data exchange with the industry reduces the amount of mistakesDuring life time also non-specialists have to prepare temporary speed restrictions They need assistance by a Tool!
10 Engineering Tool for ETCS Level 1 The described situation led to the purchase of an engineering tool extending the existing BEST simulation by VosslohMain functionsAutomatic placing of balises as a proposalManual adjustment of the proposalVisualisation of braking curves according to the type of train, speed and location of balisesIndependent verification of the engineering of ETCS level 1 supplier
11 Engineering Tool for ETCS Level 1 How to work with the toolStep 1: Basis is a fully engineered simulation of a station or lineStep 2: Add gradient valuesStep 3: Add speed profile of the lineStep 4: Start automatic placing of balisesStep 5: Verify automatic placing and adjust if desiredStep 6: Let trains run in the simulation and view the braking curves under different conditions and changes of signal aspectsStep 7: Adjust placement of infill balises and loops where desiredOR: compare with ETCS suppliers engineering for verificationOR: add TSR to view consequences

16 Results and Benefits from the development Many of the engineering rules for ETCS had to be analysed and fixed during the workThe engineering gets complex in complex topology, but could be covered by the rulesThe tool will help to standardise the engineering rulesThe limitations of ETCS level 1 can be clearly visualised to optimise the balise locations especially for TSR
