  2. 1. Characterisation of airborne particles from rail traffic

    Author : Saeed Abbasi; Ulf Sellgren; Ulf Olofsson; Mats Gustafsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne; railway; brake; block; Other engineering mechanics; Övrig teknisk mekanik; SRA - Transport; SRA - Transport; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Abstract : Since the investigation of wear particles in rail transport started in late-1910s, the high mass concentration of these particles has raised worries among researchers concerned with air quality. However, effective action has yet to be taken because of lack of relevant knowledge. READ MORE

  4. 2. Towards elimination of airborne particles from rail traffic

    Author : Saeed Abbasi; Ulf Sellgren; Ulf Olofsson; Yannick Desplanques; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Airborne; brake block; brake pad; railway; subway; TEI; wheel–rail; wear; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Abstract : Since the investigation of wear particles from rail transport started in the late 1910s, the high mass concentrations of these particles have prompted concern among researchers interested in air quality. However, effective action has yet to be taken because relevant knowledge is still missing. READ MORE

  5. 3. On wear transitions in the wheel-rail contact

    Author : Sundh Jon; Ulf Olofsson; Staffan Jacobsson; KTH; []
    Keywords : Wear transitions; Wheel; Rail; Wear regime; Wear mechanism; Mechanical engineering; Maskinteknik;

    Abstract : Wear transitions in the wheel–rail contact are of increasing interest since the general trend in railway traffic is toward increased velocities and axle loads. Curving increases the risk of flanging, causing the contact to change from an almost pure rolling wheel tread–rail head contact to more of a sliding wheel flange–rail gauge contact on the high rail in curves.
