The influence of drone flightpath on photogrammetric model quality

In 2017 the Netherlands had 7146km of railways [Ramaekers et al., 2009], which are owned and managed by ProRail and have to be frequently surveyed, for quality inspection. Surveying is done using a variety of surveying techniques, many of which require surveyors to walk on or near the tracks, which could cause injuries. An alternative surveying...

Optimising the Input Filter of Traction Installations in DC Railway Power Systems

In the world of DC railway trains nowadays, asynchronous-traction machine with traction controllers, i.e. an inverter with variable output frequency, is implemented. This controller changes the incoming DC voltage into an AC voltage of a variable frequency and RMS amplitude. The disadvantages of switching inverters, compared to a pure sine wave...

Schiphol's dynamic traffic Management: A case study on rescheduling

Around the railway station of Schiphol, railway traffic is controlled by an automated dynamic traffic management system (DVM). This system is not optimal for the future service pattern of NS and NS Hispeed. My research explores the possibilities of a new DVM by analysing different rescheduling elements by means of microsimulations in OpenTrack.

An optimization model for a Train-Free-Period planning for ProRail based on the maintenance needs of the Dutch railway infrastructure

The thesis reports on the Dutch railway infrastructure manager ProRail, on the literature study, on the determined Top 10 of maintenance activities that are determining the maintenance schedule, on the developing of the optimization model that finds such a maintenance schedule, and finally on the results and conclusions.

Evaluatie resultaten Innotrack

In het kader van het 6de Europese onderzoeksprogramma is het Innotrack onderzoek uitgevoerd. Door verschillende Europese belanghebbenden is gemeenschappelijk onderzoek gedaan naar kosteneffectieve oplossingen voor spoorwegen. De nadruk lag op innovatieve oplossingen die met een beperkte investering de onderhoudskosten kunnen reduceren. Vanuit...

Toepassingsmogelijkheden van Dynamisch Railverkeersmanagement in Arnhem

Station Arnhem staat bekend als een knelpunt in de dienstregeling. Het station zou worden uitgebreid met twee vrije kruisingen en een extra perron. Hiermee zou de punctualiteit en het aantal te verwerken treinen kunnen stijgen, zodat beter aan de wensen van reizigers tegemoet kan worden gekomen. Voor deze uitbreidingen is de komende jaren echter...
