Characterization of Non-Combustion Particulate Emissions from Rail Transport

Research output: Contribution to conferencePoster


Transport-related emissions have been in focus of environmental protection for many years. For a holistic assessment of transport-related
particulate emissions all modes of transport have to be considered. Rail transport is known as one of the most environmentally friendly
transport systems. However, in addition to combustion-related emissions, abrasion from daily operation as well as infrastructure construction
and maintenance measures represent a source of particulate matter. Studies regarding the different source contributions, particle size
distribution, composition and morphology have been scarce, making it difficult to assess the hazard potential. Therefore, further investigations
are intended to close the gaps of knowledge in the field of non-combustion particulate emissions from rail transport. In a first project, the
emission of particulate matter during infrastructure construction and maintenance work was investigated. Current investigations within the
framework of the BMDV Network of Experts, a research program financed by the German Federal Ministry for Digital and Transport (BMDV),
focus on emissions from wheel-rail, contact wire and brake abrasion. Moreover, a study on abrasion induced emissions will provide information
on the particulate morphology and its fate in the environment. Based on the overall results, an initial risk assessment can be made which will
allow a significant contribution to closing the knowledge gaps and to gain a holistic understanding of particulate emissions in rail transport.
