Assessment of safety against derailment using simulations and vehicle acceptance tests: a worldwide comparison of state-of-the-art assessment methods.

The assessment of derailment safety of new railway vehicle designs is a fundamental concern worldwide. Although the methods used for assessment in different countries and regions vary considerably, the fundamental mechanisms being addressed are the same. This paper provides a detailed review of the current state-of-the-art methods for derailment safety assessment in several regions and countries including Europe, UK, USA, and Russia. Brief overviews of the methods used in China, Korea, and Japan are also included. Similarities and differences are discussed, including testing and computer simulations. References are provided for the origins of the methods and safety performance criteria used in each region. Recommendations are made for improving the assessment methods, especially the use and validation of computer simulations. [ABSTRACT FROM PUBLISHER]
