  "description": "<p>Railway vehicles require a certain level of adhesion between wheel and rail to operate efficiently, reliably, and economically. Different levels of adhesion are needed depending on the vehicle running conditions. In the wheel tread&ndash;railhead contact, the dominant problem is low adhesion, as low adhesion on the railhead negatively affects railway operation: on one hand, the vehicle will lose traction resulting in delay when driving on low-adhesion tracks; on the other hand, low adhesion during deceleration will extend the braking distance, which is a safety issue. This thesis examines the influence of several contaminants, i.e., water, mud, leaves, oil and grease, on the adhesion in the wheel tread&ndash;railhead contact. This study will also improve our knowledge of the low-adhesion mechanism and of how various contaminants influence adhesion</p>",
