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: • Short term measures-> Applicable from 1st January 2013-> Efficient < 5 years-> Not compromising longer term measures

• Medium term measures-> Applicable, efficient and implemented < 5 years-> Not compromising longer term measures

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...

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.

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.
