An empirical study of the variability in the composition of British freight trains
As part of the broader sustainability and economic efficiency agenda, European transport policy places considerable emphasis on improving rail’s competitiveness to increase its share of the freight market. Much attention is devoted to infrastructure characteristics which determine the number of freight trains which can operate and influence the operating characteristics of these trains. However, little attention has been devoted to the composition of the freight trains themselves, with scant published data relating to the practicalities of this important component of system utilisation and its impacts on rail freight viability and sustainability. This paper develops a better understanding of the extent to which freight train composition varies, through a large-scale empirical study of the composition of British freight trains. The investigation is based on a survey of almost 3,000 individual freight trains, with analysis at four levels of disaggregation, from the commodity groupings used in official statistics down to individual services. This provides considerable insight into rail freight operations with particular relevance to the efficiency of utilisation of trains using the available network paths. The results demonstrate the limitations of generalising about freight train formations since, within certain commodity groupings, considerable variability was identified even at fairly high levels of disaggregation
Traffic congestion, reliability and logistical performance: a multi-sectoral assessment
Mitigating the Negative Environmental Impacts of Long Haul Freight Transport
Purpose - Long haul freight transport imposes huge negative environmental externalities on society. Although these can never be entirely eliminated, they can be reduced. The purpose of this chapter is to analyse some of the many mitigating measures, or interventions, that can be used. Methodology/approach - The approach used in this chapter is to review the literature and provide an overview of the main theoretical and practical mitigation measures available to transport operators. Research limitations - There are literally thousands of possible mitigation measures and combinations that can be used by operators to reduce their environmental footprint. Each of these measures warrants a separate chapter. This chapter can only present an overview of the principle available measures. Although some mainland European examples are used, it is acknowledged that the examples used are somewhat skewed towards the United Kingdom. Originality/value of the chapter - The value of the chapter is in bringing together some of the many measures and approaches that can be used to reduce the environmental externalities of long haul freight transport. Much of the information on such interventions is based on industrial and EU project sources rather than purely academic research and so is less likely to be found in academic journals. © 2014 by Emerald Group Publishing Limited.
