3. Study Overview 29 September 2011 3 Study Outline Two study stages: - Part A shall identify all prevention measures and all kinds of mitigation measures that are existing or achievable at short and medium terms. - Part B will study all prevention measures and mitigation measures based on derailment detection. - Scope is the EU-27 plus the 3 candidate countries, Norway and Switzerland. USA and Japan shall be considered in the scope of safety measure identification. Reminder:

4. Study Overview 29 September 2011 4 About Part A Task A.1: Identification of existing operation and technical rules. Task A.2: Description of the markets and technologies covered by the devices/systems in use or which may be used at the short or medium term. Task A.3: Description of the rules (inc. specific devices/systems used) in generic functional and performance terms. Task A.4: Advice on innovative measures (long term) which might be considered in a future R&D project. Part A is therefore to provide a comprehensive list of existing and potentially available measures against freight train derailment as input into Part B...

5. Study Overview 29 September 2011 5 About Part A Task A.1: Existing derailment risk measures Task A.2a: For existing technical measures, what is the market Task A.3: For ALL measures, how do they work and perform? Task A.2b: For potential NEW technical measures, what is the market Task A.4: Future Innovations? Input to Part B Input to Research Project

6. Study Overview 29 September 2011 6 About Part A Involves: - Surveys of measures via IMs, RUs, NSAs and other stakeholders. - Survey of technical systems from suppliers. - Internet research for both the above. - Existing project team knowledge. More detail on this later.

7. Study Overview 29 September 2011 7 About Part B Task B.1: Fault and event trees of freight train derailments, clearly showing the measures identified in Part A. Task B.2 - Assessment of benefits and drawbacks of existing safety rules, and of new or improved measures at short and medium terms, using data on actual/targeted performance as well as conservative assumptions. Task B.3 - top ten ranking of potentially efficient new safety measures or improvements at short and medium terms, including practical and legal implementation aspects.

8. Study Overview 29 September 2011 8 About Part B Risk model developed in Part B Populated with measures identified in Part A Leading to the identification of those that are most cost-effective Task A.1: Existing derailment risk measures Task A.2a: For existing technical measures, what is the market Task A.3: For ALL measures, how do they work and perform? Task A.2b: For potential NEW technical measures, what is the market Input to Part B

9. Study Overview 29 September 2011 9 About Part B Involves: - Collection of accident data. - Desk work to study accident data to enable risk model to be developed, - Desktop work / consultation to determine where identified risk reduction measures fit onto risk model.

10. Study Overview 29 September 2011 10 Summing Up Part A data collection, no conclusions. Part B, data analysis and assessment, with suggestion for improvement / further consideration.
