Abstract
This master thesis was produced with the intention of being a conceptual study of existing solutions and development of new solutions for a train mounted system for collection of brake dust particles from trains. Furthermore, an investigation of the risks attributable to brake dust and why the reduction of it is necessary was made. The problem was approached systematically through the adoption of Ulrich & Eppinger's methods of product development. This included collecting relevant stakeholder information, researching for existing solutions and systematically generating own solutions. Due to the substantial amounts of dust that have to be taken care of it became evident that storage was a great dilemma regarding size and cost, a fact... (More)
This master thesis was produced with the intention of being a conceptual study of existing solutions and development of new solutions for a train mounted system for collection of brake dust particles from trains.

This included collecting relevant stakeholder information, researching for existing solutions and systematically generating own solutions. Due to the substantial amounts of dust that have to be taken care of it became evident that storage was a great dilemma regarding size and cost, a fact supported by experts in the filter industry. The conclusion was to avoid proceeding with the development of train mounted dust collectors and instead focus on station-based air cleaning solutions dedicated to reducing dust from brakes as well as wear from wheel-rail abrasion and other sources.

Popular Abstract
During 2017, 353 million trips were made in Swedish subways. All these journeys led to large amounts of brake dust being emitted. According to the European Environment Agency, particulate matter smaller than 10 µm, which encompasses all brake dust, is among the most serious pollutants in terms of harm to human health, but also to the environment. One could ask whether a train mounted brake dust collector is a possible solution to solve the problem? This project has approached this question broadly, acquiring deep knowledge about the issues of brake dust and how on might go about solving it through discussions with leading experts from the air cleaning and filtration industry, train maintenance and brake equipment producers. The verdict is,... (More)
During 2017, 353 million trips were made in Swedish subways. All these journeys led to large amounts of brake dust being emitted. According to the European Environment Agency, particulate matter smaller than 10 µm, which encompasses all brake dust, is among the most serious pollutants in terms of harm to human health, but also to the environment. One could ask whether a train mounted brake dust collector is a possible solution to solve the problem? This project has approached this question broadly, acquiring deep knowledge about the issues of brake dust and how on might go about solving it through discussions with leading experts from the air cleaning and filtration industry, train maintenance and brake equipment producers. The verdict is, that it is technically possible but incredibly impractical. The main reason being the extremely fine brake particles which can only be caught with very expensive filters which in turn need substantially more frequent changing than the brake pads. Therefore a station based air cleaning systems which is dedicated to collecting brake dust is suggested, a solution which turns out to exceed the on-board solution far more than one might expect!
