Abstract:

The political force of infrastructures is often attributed to their functioning as designed, while their political afterlives remain underexplored. In this article, I explore ethnographically the phatic force of ruins of infrastructure, by dwelling on a liminal railroad segment in Romania that remains unrehabilitated many years after its breakdown. Such an open-ended state of suspension allows the isolation of infrastructure’s political and affective dimensions. The Giurgiu-Bucharest railroad met its demise in 2005 in the wake of heavy floods, producing an infrastructural gap that impacts local mobility and unravels the postsocialist social contract. State authorities and citizens engage in tactics of remediation that, while unsuccessful in resuming traffic, maintain a sense of phatic connection that kindles nostalgia for the past and frustrates anticipation of the future. These tactics make the railroad a medium for hope and at the same time a symbol for the absolute impossibility of hope.

Abstract:

The type and magnitude of loads that pass through the track superstructure have a great impact on both the design and the performance of the concrete crossties and fastening systems. To date, the majority of North American research that focus on quantifying the rail infrastructure loading conditions has been conducted on heavy-haul freight railroads. However, the results and recommendations of these studies may not be applicable to the rail transit industry due to a variety of factors. Unlike the freight railroads, which have standardized maximum gross rail loads and superstructure design practices for vehicles, the rail transit industry is home to a significant variety of vehicle and infrastructure designs. Some of the current transit infrastructure design practices, which were established decades ago, need to be updated with respect to the current loading environment, infrastructure types, and understanding of the component and system-level behavior. This study focuses on quantifying the current load environment for light rail, heavy rail, and commuter rail transit infrastructure in the United States. As an initial phase of this study, researchers at the University of Illinois at Urbana-Champaign (UIUC) have conducted a literature review of different metrics, which is used to evaluate the static, dynamic, impact, and rail seat loads for the rail transit infrastructure. UIUC will compare these methods and their computed values to determine which provide the most accurate depictions of the expected loading condition given a set of operating and infrastructure characteristics. A proper load quantification of rail transit systems, gained through an improved understanding of the load path and rail seat load, will help to establish the basis for developing recommendations for a mechanistic design process for the rail transit infrastructure components. Ultimately, the results of this research will allow transit agencies to increase the effectiveness of their capital spending and transit agencies will have the potential to improve safety, ride quality, capacity, and the life cycle of the rail transit infrastructure.

Abstract This paper sets out the evolution of international rail traffic in recent years and some of the legislative measures taken by the European Union to strengthen rail. If the same tools that have successfully been deployed for charges of domestic transport by rail are applied to cross border services, results will be systematically distorted to the detriment of cross border services.

Abstract:

Abstract The paper presents the concept of vibration measurement and reduction system for rails in hyperloop technology. It is based on the experience of measuring vibrations in high-speed rail, the first commercial magnetic rail, and vibration reduction systems for these rails. The authors outlined a conceptual vibration monitoring system based on the MQTT protocol and the vibration reduction method. The vibration reduction systems based on variable-characteristic silencers and solutions used in research centers, especially in CERNie and LIGO, were de-scribed.

Abstract:

Structural degradation of rails will unavoidably take place with time due to cyclic bending stresses, rolling contact fatigue, impact and environmental degradation. Rail infrastructure managers employ a variety of techniques and equipment to inspect rails. Still tens of rail failures are detected every year on all major rail networks. Inspection of the rail network is normally carried out at night time, when normal traffic has ceased. As the implementation of the 24-h railway moves forward to address the increasing demand for rail transport, conventional inspection processes will become more difficult to implement. Therefore, there is an obvious need to gradually replace outdated inspection methodologies with more efficient remote condition monitoring technology. The remote condition monitoring techniques employed should be able to detect and evaluate defects without causing any reduction in the optimum rail infrastructure availability. Acoustic emission is a passive remote condition monitoring technique which can be employed for the quantitative evaluation of the structural integrity of rails. Acoustic emission sensors can be easily installed on rails in order to monitor the structural degradation rate in real time. Therefore, apart from detecting defects, acoustic emission can be realistically applied to quantify damage. In this study, the authors investigated the performance of acoustic emission in detecting and quantifying damage in rail steel samples subjected to cyclic fatigue loads during experiments carried out under laboratory conditions. Herewith, the key results obtained are presented together with a detailed discussion of the approach employed in filtering noise sources during data acquisition and subsequent signal processing.

Abstract:

This article explores the design of a new wheel profile which can be used in a tram-train vehicle. A tram-train is a dual-mode vehicle that operates on two very different railway infrastructures: as a tram on light rail infrastructure and as a conventional train on heavy rail infrastructure. The challenges of wheel–rail interface have been highlighted and discussed, and the analysis and design process required to develop an optimised wheel profile for dual-operation running have been presented. One of the key issues in developing a dual-operation wheel profile was managing the contact conditions within the wheel–rail interface. The interface is critical not only to the safe running of the vehicle but also to maximise asset life and to minimise wheel–rail damage. A combination of vehicle dynamic simulations and bespoke software was used to allow the development of a new wheel profile for tram-train operations.

Abstract:

Suburban light rail transit (LRT) and regional rail systems face similar challenges when it comes to upgrade perspectives. A particular planning process is required for upgrade measures apart from conventional alignment modifications. This study investigated the similarities between LRT and regional rail characteristics and developed a robust decision framework that linked demand modeling, timetable construction, and infrastructure design in an integrated approach. The study applied a three-stage planning process for a regional railway system in a midsized Austrian city. A multimodal travel demand model that included demographic changes over the next 2 decades was used. Travel demand was calculated with the current timetable and forecasted changes in regional planning. Within a sensitivity analysis, the impact of alternative timetables on modal shift was checked. A detailed analysis of these results was undertaken to optimize the best-ranked timetable model. Different infrastructure measures such as electrification, double-track sections, road grade crossings, station layout, and alignment changes were identified to match the optimal target timetable with fixed hub-to-hub travel times. Various stakeholders were involved in deciding the political objectives of modal shares, transit headways, and regional rail infrastructure. A well-defined planning process with fixed milestones led to a common agreement on a stepwise upgrade plan for the next 25 years. The proposed method can be applied to regional rail as well as LRT.

Abstract Funding and financing arrangements for railway infrastructure in Europe are often perceived as complex and opaque. Given the large sums of public money involved, greater transparency on inputs and outputs is required. This paper aims to present an overview of rail infrastructure funding and financing in Europe based on recent evidence, and draws comparisons with the systems in the US and Japan. We also discuss a number of policy options to address the funding gap and ensure that European railways improve their financial viability and remain strong pillars of sustainable mobility in the future.

Abstract:

The article presents evolution of EU’s regulations referring to the rules of calculation of access charges for rail infrastructure. In the opposite to payable utilization of road, harbor or airport infrastructure, payable access to the rail infrastructure for transport operators (rail carriers) is a relatively new issue in the European railways, because it emerged just in 1991 in relation with taken up system reforms of EU’s rail sector. In the introductory part of the article, the Directive 91/440 has been indicated as a historically first law act that referred to the issue of calculation of access charges for rail infrastructure. Next, there were presented regulations of the Directive 2001/14 adopted within so called first railway package and vagueness in their interpretation, which led to the trials before the European Court of Justice, whereas the most important was the one against Poland, ended with the sentence on the 30th of May 2013. The final part of the article presents references to this sentence and to the new regulations referring to the charges for the access to rail infrastructure, included in the Directive 2014/34 and executive ordinance 2015/909 issued on its basis.

Abstract:

Digital transformation in the railway industry is an important element in the development of railways and should benefit commuters, railway operators, infrastructure managers and rolling stock manufacturers. The process of digitization applies to two domains, i.e. customer service and railway companies’ operation. This paper aims to present previous eff orts regarding the use of digital technologies in customer relations and in the field of operations and maintenance, which translates into the quality of services provided. This paper highlights important concepts of this domain with respect to passenger and freight transport, infrastructure, railway rolling stock and railway traffic management. It is also argued that the process of digitization needs properly trained staff . Examples of innovative initiatives of Polish and European railway companies are covered. Keywords: railway transport, digitization, digitization of the railways

Abstract:

Purpose The purpose of this paper is to present a framework for maintenance analytics that is useful for the assessment of rail condition and for maintenance decision support. The framework covers three essential maintenance aspects: diagnostic, prediction and prescription. The paper also presents principal component analysis (PCA) and local outlier factor methods for detecting anomalous rail wear occurrences using field measurement data. Design/methodology/approach The approach used in this paper includes a review of the concept of analytics and appropriate adaptation to railway infrastructure maintenance. The diagnostics aspect of the proposed framework is demonstrated with a case study using historical rail profile data collected between 2007 and 2016 for nine sharp curves on the heavy haul line in Sweden. Findings The framework presented for maintenance analytics is suitable for extracting useful information from condition data as required for effective rail maintenance decision support. The findings of the case study include: combination of the two statistics from PCA model (T2 and Q) can help to identify systematic and random variations in rail wear pattern that are beyond normal: the visualisation approach is a better tool for anomaly detection as it categorises wear observations into normal, suspicious and anomalous observations. Practical implications A practical implication of this paper is that the framework and the diagnostic tool can be considered as an integral part of e-maintenance solution. It can be easily adapted as online or on-board maintenance analytic tool with data from automated vehicle-based measurement system. Originality/value This research adapts the concept of analytics to railway infrastructure maintenance for enhanced decision making. It proposes a graphical method for combining and visualising different outlier statistics as a reliable anomaly detection tool.

Abstract:

Failure to realize the schedule which is primarily reflected in train delays is the direct consequence of insufficient availability of capacities of the current railway infrastructure which are generated by low level of usable quality of the track network in general. The aim of the research presented in this paper is to determine the method of optimal interventions of the rail infrastructure managers and traffic control activities on the reduction of the influence of slow runs and line closures thus ensuring a sufficient number of rail routes for the customers’ needs and consequently higher quality realization of the schedule. The paper gives a concrete presentation of the volume of slow runs and line closures, calculation of reducing the level of railway capacities with a simulation and the result of this condition on the capacity of the concrete railway line and the proposal of a model for organizing an expert group within the traffic control activities for the fastest possible elimination of these negative phenomena.

Abstract:

Traditionally, railway inspection and monitoring are considered a crucial aspect of the system and are done by human inspectors. Rapid progress of the machine vision-based systems enables automated and autonomous rail track detection and railway infrastructure monitoring and inspection with flexibility and ease of use. In recent years, several prototypes of vision based inspection system have been proposed, where most have various vision sensors mounted on locomotives or wagons. This paper explores the usage of the UAVs (drones) in railways and computer vision based monitoring of railway infrastructure. Employing drones for such monitoring systems enables more robust and reliable visual inspection while providing a cost effective and accurate means for monitoring of the tracks. By means of a camera placed on a drone the images of the rail tracks and the railway infrastructure are taken. On these images, the edge and feature extraction methods are applied to determine the rails. The preliminary obtained results are promising.

Abstract:

In this paper, a real option approach to determine the optimal time to execute interventions on rail infrastructure, when it is not known for certain which intervention is to be executed, is presented (i.e. the optimal intervention window). Such an approach is useful in the management of rail infrastructure that belongs to a multi-national rail corridor where multiple railway organizations, ideally, should coordinate their maintenance interventions, years in advance, to minimize service disruptions. The approach is based on an adaptation of the Black and Scholes differential equation model used to value European call options in financial engineering. It is demonstrated by determining the optimal intervention window for infrastructure in a fictive rail corridor.

Abstract:

Heavy haul railway track infrastructure are commonly equipped with balloon loops to allow trains to be loaded/unloaded and/or to reverse the direction of travel. The slow operational speed of trains on these sharp curves results in some unique issues regarding the wear process between wheels and rails. A wagon dynamic system model has been applied to simulate the dynamic behaviour in order to study the wheel–rail contact wear conditions. A wheel–rail wear index is used to assess the wear severity. The simulation shows that the lubrication to reduce the wheel–rail contact friction coefficient can significantly reduce the wear severity. Furthermore, the effects of important parameters on wheel–rail contact wear including curve radius, wagon speed and track superelevation have also been considered.

The focus of this paper lies on monitoring of the track sections with rail corrugations caused by wheel sliding. Short waves on the running surface of the rail head on low rail are typical for this defect. Long-pitch corrugation is a significant cause of vibration and noise pollution in the railway infrastructure. Therefore it is very important to understand the formation and development of this imperfection of the rails. Measurements were carried out in curves of small radii on several tracks in the Czech Republic. In addition to the measurement of the surface of the rail head a number of supplementary parameters was evaluated for each section, such as curve radius, superelevation, track gauge etc. and the speed of passing trains as well. This paper describes rail corrugation defect and its development. Our early results are presented in the Conclusions.

Abstract:

Recent developments in the technology of a modern embedded rail system grant many new possibilities for improving the railway infrastructure. An embedded rail system significantly reduces noise and the dynamical impact affecting both the infrastructure and the rolling stock itself. An embedded rail system may be used for constructing any type of railway infrastructure including high-speed railways. Its attributes are also suitable for modernization of the current steel railway bridges or constructing new structures, where slender bridge decks are required. However, in a railway track equipped with an embedded rail system, stress increments rise due to its restricted expansion movement. This effect is naturally higher when the embedded rail system is placed on a bridge, because of their different deformation possibilities. For a wider use of embedded rail system, examining the interaction behavior between the embedded rail system and the substructure is a matter of essential importance. Furthermore, the nonlinear character of embedded rail system polymer-based components needs to be considered when examining their interaction behavior. Therefore, this paper aims at investigating the nonlinear coupling functions of an embedded rail system under the effects of temperature and load rate. For this purpose, a comprehensive analysis consisting of laboratory experiments, material tests of the embedded rail system components and subsequent numerical validation was performed. Results are concluded in the paper.

Abstract:

The permanent way components are of key importance for safe operation of a rail way. The country regulations, in particular in Ukraine, specify the operational life limits for the permanent way but they do not define any tool or method to predict deterioration of the permanent way condition over time. The study is aimed to develop a method for assessing failure risk of the permanent way components in operation. There was a method offered to evaluate risk of failure of the permanent way components of the welded tracks, which considers accumulated freight load on a rail section. Each element of the permanent way, such as rails, fasteners, sleepers, ballast layer, accumulates defects and deformations. The accumulation rate is different for the above components and depends on freight traffic. There was probability of failure-free operation calculated for each component for the first time and an integral fatigue index of the construction has been offered which considers freight traffic accumulated load. There was a mathematical failure forecast model developed which allows planning of track maintenance. The model allows to take into account operating conditions of a railway section. The results of simulation are presented in various diagrams.

Abstract:

One of the main priorities of transport policy in the EU is to take measures to support railway transport as an environmentally friendly transport mode. An interesting challenge for a railway transport operation is represented with cost items for its operation. This problem is exacerbated if transport flows are routed through a congested railway infrastructure. If some or all transport takes place on congested rail infrastructure, the carrier’s costs increase, which may ultimately lead to withdrawal from the market. The article deals with the impact of insufficient capacity on the rail carrier’s costs. We used a pre-cost calculation methodology to calculate the rail carrier’s additional costs due to the insufficient railway network capacity based on detailed calculation of train costs and proposed a methodology for carrier decision-making in case of insufficient rail infrastructure capacity. The case study showed that the use of a diversion track in case of insufficient planned rail line capacity may not be advantageous for carriers, even with a longer waiting time for capacity to be released. One of the ways to eliminate the negative effects of congested railway infrastructure is investment in the increase of its capacity.

Abstract:

Abstract. Critical infrastructures in Shanghai have undergone uneven settlement since their operation, which plays an important role in affecting the security of Shanghai. This paper, taking rail transportation as example, investigates settlement characteristics and influencing factors of this linear engineering, based on long-term settlement monitoring data. Results show that rail settlement is related to geological conditions, regional ground subsidence, surrounding construction activities and structural differences in the rail systems. In order to effectively decrease the impact of regional ground subsidence, a monitoring and early-warning mechanism for critical infrastructure is established by the administrative department and engineering operators, including monitoring network construction, settlement monitoring, information sharing, settlement warning, and so on.

Abstract:

In recent years, China keeps working on restructuring the country’s multimodal transport and highly develops the high-speed rail (HSR) infrastructure to improve transport efficiency. As the economic engine of China, the Yangtze River Delta region keeps leading the HSR development and the transporting modal transformation within the whole country. The fast development of HSR on the one hand highly improves passengers’ travel efficiency and, on the other hand, releases the capacity of conventional rail infrastructures to support regional multimodal freight transport. This study applies a three-level AHP structure and constructs a comprehensive index to evaluate the development of a rail-based multimodal freight transport network including railway, rail-water, and rail-road. The comprehensive index contains 14 quantitative and 8 qualitative indexes, covering the rail-based infrastructures, multimodal transport capability, freight transport performance, and transport sustainability. The comprehensive index is then applied to analyze the rail-based multimodal freight transport for the Yangtze River Delta region. The operational data of 59 freight stations and more than 200 railway links of the Yangtze River Delta were recorded. About 172 valid questionnaires were collected to score the qualitative indexes, and all the quantitative indexes are scored based on the real-life freight data. The results reveal the impacts of HSR development on rail freight transportation and show that Zhejiang has led rail freight transportation while Shanghai mainly leads the waterway freight transportation. Meanwhile, Anhui performs very well on road-rail transportation and Jiangsu has made a great improvement on water-rail transportation.

Abstract:

Urban rail transit is an important form of infrastructure for a city or even a country. This paper uses location entropy to measure the industrial agglomeration level of cities at the prefecture level or above in China from 2006 to 2018 and empirically tests the mechanisms of urban rail transit construction, factor agglomeration, and industrial agglomeration. The empirical results show the following: (1) the construction of urban rail transit infrastructure has a significant positive effect on the agglomeration of the labor force, capital, and technological innovation; (2) urban rail transit construction effectively induces agglomeration in the urban manufacturing industry and consumer service industry; and (3) the impact of urban rail transit construction on agglomeration in the urban manufacturing industry and consumer services industry is primarily due to the intermediary effects of factor agglomeration. The results show that gradually improving the urban rail transit network, strengthening the construction of comprehensive rail transit hubs, and optimizing capital allocation within urban rail transit allow for the full utilization of urban rail transit construction in promoting industrial agglomeration.
