Railway transition zones represent a significant challenge due to abrupt variations in substructure properties, leading to differences in vertical strain. These differences cause the wheel-rail dynamic interaction to get excited, which can cause passenger discomfort, track deteri ...

Exploration of the design space for a sustainable Overhead Contact Line support structure on the Dutch main rail network

An Integrated Approach to Sustainable Design: Multi-Disciplinary Analysis and Multi-Objective Optimisation using the NSGA-II Algorithm

The Overhead Catenary Line System (OCLS) is crucial for continuous electrical supply to trains in electrified railway networks. This article outlines the research conducted on the exploration of the sustainable design space of the Overhead Contact Line support structure on the ma ...
Transition zones in railway tracks are locations with an abrupt change in stiffness in the vertical rail supporting structure. These locations are typically located as approaches near engineering structures where there is a sudden change in track substructure. Due to these abrupt ...

De statische wissel

De wissel die nooit faalt

Dit rapport behandelt een wissel die geen bewegende delen bezit en hierdoor geen controle circuit nodig heeft. Het rapport bezit een analyse van verschillende bestaande wissels en wisselconcepten, beide in hoofdspoor en tramspoor, om een evaluatie te geven van elk concept. Op dez ...
In het gebied Apeldoorn – Dieren ligt een oude spoorlijn van de Veluwsche Stoomtrein Maatschappij die op dit moment alleen nog voor toeristisch gebruik wordt geëxploiteerd. Om de bereikbaarheid van het gebied te vergroten wordt er onderzoek gedaan naar de mogelijkheid om hier ee ...
In this thesis Axle Box Acceleration (ABA) data is used to determine the health condition of Insulated Rail Joints (IRJs) to investigate the potential of ABA data in predictive maintenance. Using frequency characteristics from the Continuous Wavelet Transformation (CWT), the main ...

Circularity in Railway

How circularity can be applied in railway

Track quality measures differ from standard to standard. Widely used indices for track quality are the standard deviations of the rail longitudinal level data and the standard deviations of alignment data. Researchers have opted for various learning methods as to relate track qua ...

ATO

Automatic train operation

Het aantal treinreizigers stijgt elk jaar. Binnenkort zal de huidige capaciteit van het treinvervoer worden
overstegen. Een oplossing voor dit probleem is het automatiseren van treinen. Rijden onder automatic
train operation (ATO) gaat in verschillende stappen. De hogere ...
Soil is an important part of a railway track structure. It provides the foundation for the structure and distributes the imposed loads. Consequently, soil has an influence on the condition of a track structure and a low quality soil can ultimately cause failure of the track struc ...
Nederland heeft ongeveer 7000 km spoor en bij het onderhoud daaraan komt er jaarlijks ongeveer 500 duizend ton aan ballast vrij. Het zou dus mooi zijn als dit allemaal hergebruikt kan worden. Maar doordat het ballast tijdens de levensduur vervuild en versleten raakt kan dit niet ...
Crossings are important yet vulnerable parts of a railway network. This warrants that, in the Netherlands (a country with high traffic loads), crossing geometry is measured twice per year by dedicated measurement vehicles. This produces so much (point cloud) data that prioritizin ...

Plastic railway sleepers

Creating a finite element model for hybrid plastic railway sleepers

Railway sleepers form an important part of a classic track structure. Sleepers exists in their current form for a long time. The transition from wood to concrete sleeper has been made, but wood is still used and present in many track sections. As creosoted wooden sleepers are not ...

Dynamic behaviour of slab track on pile foundation

Analysis method based on dynamic behaviour of a high-speed slab track and settlements in the substructure

In this master thesis the behaviour of a high speed railway track constructed on top of a pile foundation with settlements under a dynamic load has been analysed. Therefore, a model was developed in the software program DARTS, dynamic analysis of rail track structures. In DARTS t ...
Transitiezones zorgen in de railbouwkunde al geruime tijd voor problemen. De werkelijke oorzaken van deze overgangen van regulier spoor naar een civiel kunstwerk blijven onduidelijk, terwijl de onderhoudskosten significant hoger zijn ten opzichte van andere delen van het spoor. D ...

3- en 4-puntsbuigproef van een kunststof dwarsligger

Is een gewapende kunststof dwarsligger geschikt voor de Nederlandse spoorwegen op basis van 3- en 4-puntsbuigproeven?

Sinds 23 april 2019 is het verboden om hout met creosoot te behandelen. Hierdoor zijn de houten spoordwarsliggers een stuk minder duurzaam. Lankhorst Mouldings Sneek-Holland heeft 2 gewapende kunststof dwarsliggers ontworpen die een stuk duurzamer zijn, namelijk een HDPE-dwarslig ...

Inspecting crossing geometry

Tool development for manual inspections of crossing geometry

Turnouts allow trains to change from one track to another. Therefore, they are an essential part of infrastructure to create and operate a railway network. This project focuses on the (common) crossing; the part of the turnout where the inner rails cross through one another. Beca ...

Assessing crossing geometry

Expert tool for numerical and experimental assessment of turnout crossing geometry

This thesis project discusses the development of a fast assessment tool for the performance of railway turnout crossings. The assessment tool is developed in Matlab and allows the user to swiftly set up a model and assess the performance. The rail geometry input can be either des ...
The current 1.5kV railway traction power supply system is reaching its limits in the Netherlands and therefore, ProRail is investigating the replacement of this system by the 3kV railway traction power supply system. This study will investigate how effective the 3kV traction powe ...
