Abstract

Traditional empirical methods of designing railway track rely on simplistic impact factor methods that crudely represent the complex dynamic behaviour of track and train interaction and of the defects that give rise to damaging forces. Various analytical models have been developed around the world to help the track design engineer better understand the consequences of variations and innovations in track design. The creators of six recently developed models from Canada, China, Germany, Sweden, USA and UK were invited to participate in a benchmarking exercise to allow comparison of the operation, outputs and applicability of those models. Although detailed instructions were given to the benchmark participants, variations in interpretation, complexity and underlying theory of each model led to differences in outputs. This paper provides some guidance in interpreting these differences and compares the results to those obtained from traditional design processes.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
