1. 1. Modeling fault probability in single railroad turnouts in Eastern Region, Sweden, with the use of logistic regression models : A step from preventive to predictive preventive maintenance in railway maintenance planning

   University essay from KTH/Transportplanering

   Author : Filipp Zarov; [2019]
   Keywords : maintenance planning; railway turnouts; malfunction probability modeling; object-oriented databases; logistic regression models; underhållsplanering; spårväxlar; felsannolikhet modellering; objektorienterad databas; logistiska regressionsmodeller;

   Abstract : Turnouts are an important part of railway infrastructure for two reasons: infrastructure andmaintenance. For the infrastructure they provide the flexibility to allow the formulation and branchingof railway network and for maintenance they consume a large part of maintenance budget and have aprominent place in maintenance planning policy and activities.

4. 3. Investigation of the behaviour of return collectors on Paris’ subway MP05 (Line 1)

   University essay from KTH/Järnvägsteknik

   Author : Theo Le Bars; [2014]
   Keywords : Rubber-tyred subways; return collector; rigid solid mechanics; contact.;

   Abstract : Return collectors are predominant organs for rubber-tyred subways to operatesince they ensure both the track circuit shunt and the traction current return. Po- sitioned at the interface between the track and the rolling stock, they are subjected to the disruptions linked to the train movement and the track irregularities. READ MORE

5. 4. Influence of Switches and Crossings on Wheel Wear of a Freight Vehicle

   University essay from KTH/Spårfordon

   Author : Emmanouil Doulgerakis; [2013]
   Keywords : dynamic vehicle-track interaction; turnout; switch crossing; wheel wear; wheel-rail contact geometry;

   Abstract : Turnouts (Switches & Crossings) are important components in railway networks, as they provide the necessary flexibility for train operations by allowing trains to change among the tracks. But the turnout’s geometry with discontinuity in rail profiles and lack of transition curve causes additional wear both on track and on vehicle. READ MORE
