Railways are increasingly investing in their infrastructure to achieve sustainability objectives and meet expected growth in demand for rail transport services. Since building new physical infrastructure requires large-scale investments and long lead times, many infrastructure managers (IMs) are prioritizing upgrades to their signalling systems...

This thesis aims to contribute to the policy debate on the complexity of passenger rail markets and to provide recommendations for the Dutch market. An extensive literature review has been conducted to identify the policy issues that must be discussed when dealing with passenger rail markets. These issues are structured in a theoretical...

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 changes the dynamic forces of the wheel-rail interaction on the...

Wheel-rail high-frequency interaction is closely related to the formation of railway short-wave defects. Finite element (FE) method has been widely used to simulate wheel-rail dynamic systems, but its validity in modelling high-frequency interaction has not been fully demonstrated in three dimensions (3D). This work aims at comprehensively...

Polygonal wear is a type of damage commonly observed on the railway wheel tread. It induces wheel-rail impacts and consequent train/track components failure. This study presents a finite element (FE) thermomechanical wheel-rail contact model, which is able to cope with the three possible generation and development mechanisms of polygonal wear...

The present study focuses on the application of finlet rails as a passive technique of flow control to mitigate trailing-edge noise. Finlet rails are small cylinders whose axes are aligned along the streamwise direction, transversally positioned with respect to the trailing edge. In the first part of this study, the effects of finlet geometry...

Short pitch corrugation has been a problem for railways worldwide over one century. In this paper, a parametric investigation of fastenings is conducted to understand the corrugation formation mechanism and gain insights into corrugation mitigation. A three-dimensional finite element vehicle–track dynamic interaction model is employed, which...

This paper aims at identifying the formation mechanism of short pitch rail corrugation using an improved configuration of a 1/5 scaled V-Track test rig. The loading conditions of the V-Track are designed to simulate the wheel-rail dynamic interactions on the tangent track. Corrugation initiation and consistent growth are successfully produced...

This work presents the results of a measurement campaign to demonstrate the effectiveness of the axle box acceleration (ABA) technology for detecting rail defects. The measurements were conducted along the Iron Ore line between Sweden and Norway for the IN2TRACK3 project. This line is mostly single-track with passenger-freight mixed traffic and...

Short-haul flights, known for their high carbon intensity relative to distance, are increasingly challenged by high-speed rail (HSR), a viable and environmentally friendly alternative. This study develops a model adapting the “Transit Network Design and Frequency Setting Problem” to high-speed rail, focusing on optimizing existing networks...

This thesis describes the design of a 3rd order 1-bit delta-sigma modulator whose input-signal range (0 to 1.95V) exceeds its supply voltage (1.2V). By using a passive input stage and a single-OTA resonator, this beyond-the-rails modulator realizes a 3rd order loop filter with only two amplifiers instead of the usual three and thus achieves...

Following the European Green Deal, transport- related emissions must be reduced by 90% in 2050. While aviation contributes to a significant share of these emissions, the substitution of flights for rail travel is often considered to achieve a reduction in emissions of greenhouse gasses. Mostly, travelers consider this option when the full trip...

In the era of increasing global connectivity, Schiphol Airport aims to transform into a Multimodal Transport Hub (MTH) to meet the growing demand for seamless travel experiences. This shift from the traditional hub-and-spoke model to an MTH not only enhances passenger satisfaction but also positions Schiphol as a leader in the aviation industry...

The Ministry of Infrastructure and Water Management set up the ERTMS Programme and commissioned ProRail to realize the rollout. In Dutch vernacular, ERTMS is often used, but the system that replaces the legacy dutch system is ETCS Level 2. This rollout of ETCS Level 2 in infrastructure is currently being done on 7 sections of track in...

High-speed rail (HSR) is gaining increasing attention due to its sustainability and transport capacity, aligning with ambitious European transport goals for 2030 and 2050. Despite its potential, the creation of a unified European HSR network faces challenges rooted in poor coordination and national interests. This study addresses the absence of...
