Abstract
Even if the emission sources are identified, there is a lack of valid data about particulate matter (PM) emissions of railways. In order to deepen the knowledge about PM emissions the Austrian Federal Railways (ÖBB) initiated a research project. Extensive PM monitoring was carried out within a single-tube double-track tunnel in Austria. Results gained gave the possibility to derive non-exhaust PM emission factors for various train types. It turned out that freight trains caused higher emissions by a factor of 7 compared to passenger trains. An analysis of filter samples gave information about the dust composition. According to that roughly 40 % of the total emitted PM mass could be assigned to iron particles. Additionally some small amounts of Copper, Manganese and Zink were identified.
