2. Study Overview 06 May 2011 2 About DNV Independent foundation with around 9,000 employees. Det Norske Veritas (DNV) was established in 1864 in Norway. 300 office in 100 countries.

3. Study Overview 06 May 2011 3 Rail Capabilities Notified Body and ISA services to the rail industry. Audit and certification, e.g. IRIS for the rail sector. 100s of rail safety studies in the past. Written and maintain software for rail performance modelling, used extensively by Network Rail, RailCorp and others for performance prediction and asset testing purposes.

4. Study Overview 06 May 2011 4 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:

5. Study Overview 06 May 2011 5 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...

6. Study Overview 06 May 2011 6 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

7. Study Overview 06 May 2011 7 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.

8. Study Overview 06 May 2011 8 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.

9. Study Overview 06 May 2011 9 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

10. Study Overview 06 May 2011 10 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.

11. Study Overview 06 May 2011 11 Summing Up Part A data collection, no conclusions. Part B, data analysis and assessment, with suggestion for improvement / further consideration.
