Mitigation matrices for derailment prevention Railway Days| Bucuresti| 8 th - 9 th Oct Theme [SST ] Development of the Future Rail System to reduce the Occurrences and Impact of Derailment. Andreas Schöbel, Thomas Maly Vienna University of Technology Allan Zarembski University of Delaware

Research project Funded by the European Commission (Seventh Framework Programme) 3 Year Project Commencing October 2011 (Total Budget €4,800,000) 2 D-RAIL

Background 3  European rail freight is of strategic and economic importance  Derailments cause major network disruption and societal impact  Large number (low cost) - Small number (high cost)  ERA initiative to reduce freight train derailments supported by EC  Emerging research indicates potential for major step forward

Objectives D-RAIL project aims to provide significant improvements in the detection and prevention of derailments and mitigation of their subsequent effects.  To provide cost-effective solutions to reduce the occurrences of freight train derailments across Europe by %.  To reduce derailment-related costs by 10 – 20% through improved mitigation measures. 4

CONSORTIUM 5  Twenty partners from across Europe with a wide geographical representation  Partners include Infrastructure providers, operators, industry and academia Project is jointly co-ordinated by Newcastle University and UIC  Global project which includes International Railways (UIC), Russia (RZD) and USA (Harsco)  Many of our partners also have significant International rail experience outside the EU
