The aim of the thesis is twofold: to analyze the effects of the expectations on the Bothnia Line on the housing market and expectations on railway use. To fulfill these aims, three questions are considered: 1. To what extent is property prices influenced by the expected effects of the Bothnia Line? 2. Are there differences in expectations on regional development and future journeys between residents in different locations and with different individual characteristics? 3. How are trips to work affected by the expectations on the Bothnia Line and the performance of the train service according to residents in different locations? Property prices are investigated quantitatively with data delivered from Lantmäteriet. The data contains every sold property from 1994 to 2001 in the municipalities of Umeå, Nordmaling, and Örnsköldsvik. Expectations on regional development and future traveling on the Bothnia Line were investigated with two questionnaires conducted in the autumn of 2002. The empirical results from the study of property prices are clear. There are no signs of influence from the Bothnia Line on the property prices close to the railway stations or in the proximity of the railway. The empirical results from the questionnaires reveal a mixed picture of the expectations. In the municipalities located furthest away from the railway, the expectations are low. On the contrary, a large proportion (>75 %) of the residents in municipalities along the railway line believe it can be useful for the population in general when searching for new employment opportunities. This is especially true for males living in Örnsköldsvik. A significantly smaller proportion (≈25 %) believes they will use the railway themselves. One explanation to the geographic variations is that they are a result from an ongoing diffusion process. Residents in Örnsköldsvik were the first ones to have a visual image of the railway since the construction started there. As the construction continues, the expectations might increase in other locations as well. Another possibility is that people only react on word of mouth from someone that actually made a trip before they consider changing the mode of transport. If that is the case, the expectations will increase only after the opening of the railway line. With the exception of residents in Nordmaling, expectations on future journeys with the Bothnia Line are low. The low expectations on journeys on the Bothnia Line might be explained by the lack of attraction between the places along the line. They are satisfied with their present situation and cannot find any rationale to consider other alternatives. It is a different story if they are forced to consider other alternatives. The result from a stated preference study shows that if they are offered employment at another place, the majority is willing to commute.

The aim of this thesis is to understand the conservation and transformation problems of railway heritage and to prepare a conservation and transformation principles for Iskenderun railway area. Primarily, it is tried to understand the historical process and the current situation of conservation of railway areas. In addition, in this study theoretical and historical framework of transformation of railway areas is developed in the light of international charters and documents. Transformation examples from Turkey and Europe were searched with analyzing the railway system and transformation approaches of the countries. In order to prepare a conservation and transformation principles for Iskenderun terminus area, considering the direct relation of the railway site with the port site, a wide border including the port for the study area is chosen and a detailed analyzes were done for whole area. For this study, the major concern is establishing strong principles in different scales. It is important to guide each conservation and transformation projects in Turkey. For rooted solutions, regulations have to start in the transformation strategies and railway policy.

Ground-borne vibrations from railway systems not only pose threats to structural integrity of nearby buildings and cause annoyance on people but also contribute into environmental noise levels. It is of utmost importance to predict these vibrations at the design stage of such systems. This thesis attempts to reach this goal through finite elements analysis. Commercial software is used to develop a finite element model of an existing railway system. The model is based on the work of Forrest and Hunt [11]. It is also aimed to perform transient analysis in time domain to complement vibration information already obtained in frequency domain. The model is validated by checking maximum element size and comparing results with the infinite boundary condition case. Parametric studies are designed to investigate effects of soil type, railpad type and train speed on vibrations induced by underground train traffic. Results acquired through the finite element analysis are found to be in good harmony with the ones by existing numerical methods. The study demonstrates that the approach can be applied to predict ground-borne vibration from any configuration of railway systems.

Railway track stiffness (vertical track load divided by track deflection) is a basic parameter oftrack design which influences the bearing capacity, the dynamic behaviour of passing vehiclesand, in particular, track geometry quality and the life of track components. Track stiffness is abroad topic and in this thesis some aspects are treated comprehensively. In the introductionpart of the thesis, track stiffness and track stiffness measurements are put in their propercontext of track maintenance and condition assessment. The first aspect is measurement of track stiffness. During the course of this project, Banverkethas developed a new device for measurement of dynamic track stiffness called RSMV(Rolling Stiffness Measurement Vehicle). The RSMV is capable of exciting the trackdynamically through two oscillating masses above one wheelset. The dynamic stiffness is acomplex-valued quantity where magnitude is the direct relation between applied load anddeflection (kN/mm) and phase is a measure of deflection-delay by comparison with force. Thephase has partial relationship with damping properties and ground vibration. The RSMVrepeatability is convincing and both overall measurements at higher speeds (up to 50 km/h)and detailed investigations (below 10 km/h) can be performed. The measurement systemdevelopment is described in Paper A and B. The second aspect is evaluation of track stiffness measurements along the track from a trackengineering perspective. Actual values of stiffness as well as variations along the track areimportant, but cannot always answer maintenance and design related questions alone. InPaper D track stiffness is studied in combination with measurements of track geometryquality (longitudinal level) and ground penetrating radar (GPR). The different measurementsare complementary and a more reliable condition assessment is possible by the combinedanalysis. The relation between soft soils and dynamic track stiffness measurements is studiedin Paper C. Soft soils are easily found and quantified by stiffness measurements, in particularif the soft layer is in the upper part of the substructure. There are also possibilities to directlyrelate substructure properties to track stiffness measurements. Environmental vibrations areoften related to soft soils and partly covered in Paper C. One explanation of the excitationmechanism of train induced environmental vibrations is short waved irregular supportconditions. This is described in Paper E, where track stiffness was evinced to have normalvariations of 2 – 10 % between adjacent sleepers and variations up to 30 % were found. Anindicative way of finding irregular support conditions is by means of filtering longitudinallevel, which is also described in the paper. Train-track interaction simulation is used in PaperH to study track stiffness influence on track performance. Various parameters of trackperformance are considered, e.g. rail sectional moment, rail displacement, forces at wheel-railinterface and on sleepers, and vehicle accelerations. Determining optimal track stiffness froman engineering perspective is an important task as it impacts all listed parameters. The third aspect, efficient maintenance, is only partially covered. As track stiffness relates toother condition data when studied from a maintenance perspective, vertical geometricaldefects (longitudinal level and corrugation/roughness) are studied in paper F. The generalmagnitude dependency of wavelength is revealed and ways of handling this in conditionassessment are proposed. Also a methodology for automated analysis of a large set ofcondition data is proposed in Paper G. A case study where dynamic track stiffness,longitudinal level and ground penetrating radar are considered manifests the importance oftrack stiffness measurements, particularly for soil/embankment related issues. / QC 20100623

The mainline railway track between Dublin and Belfast in Northern Ireland was constructed during the 1850's. Substantial lengths of railway embankment were constructed over poor-quality peaty soils. This was accomplished using tree trunk fascines placed directly on the natural ground surface; with poor-quality local peaty soils used as light weight fill.<p>In recent years, Northern Ireland Railways have noticed that these sections of railway track have been deteriorating more rapidly than sections of the track where the foundations are more competent. The magnitudes of displacement of the track under train loading appear to be increasing gradually over time and train speeds have had to be reduced.<p>This thesis is based on the research done to monitor the response of these railway track and embankment structures to dynamic train loading. The displacements were monitored for two different embankments under a variety of loading conditions and for various seasonal conditions. These displacements were recorded using a sensor created for this task. The sensor consisted of a photo-sensitive array mounted on the sleepers and a laser, which was placed outside the area of influence of train loading, and shone on the photo-sensitive array. <p>Analytical (Winkler) modelling was conducted to determine the effects of train speed and the cause of the large train-induced displacements. Analytical and finite element modelling were used to determine the effectiveness of alternative methods of embankment stabilization.<p>The results from the analytical modelling suggest that the deformation of the embankment under train loading was not due to dynamic excitation, but static deformation of the poor-quality fill and soft foundation materials. From both the analytical and finite element modelling of possible remediation techniques, methods that stiffen the embankment and foundation material are shown to be the most effective at reducing the train induced deflection of the embankment.

Sudbury serves as a relevant historical case study of a settlement that has undergone several transformations since its inception as a fledgling village in the latter part of the nineteenth century. Though changes of this kind have been frequent in Ontario, they have not normally happened to hinterland resource communities. This article suggests that Sudbury is unique in this regard, having evolved through five distinct stages: (I) a railway company village, (2) a colonial-frontier mining town and city, (3) a regional central-place, (4) a declining metropolis, and (5) a nearly selfsustaining community. The constant restructuring of Sudbury's society and economic base has been caused by a variety of external and internal forces, among which the "human dynamic" has been vital and ever present. The paper suggests that under certain circumstances a resource community can progress from a staples and boom-bust existence to a more sustainable urban economy based on local and regional influences.

The object of this thesis is to analyze the evolution of railway interoperability and safety in Europe in the period 1991-2011. This pretends to assess what has been the legislative process at EU level in the last 20 years. This analysis looks for to determine whether it has been established the strong enough bases to achieve fully interoperable Trans-European Railway Network in a reasonable time, with uniform security features. The second aspect is to determine those points that should be corrected and improved, or simply addressed, to accelerate the integration process. A common feature of the rail networks in the European countries is their strong national focus in regard to Railway traffic rules and technical standards. This leads to specific products often developed and implemented by the national industry. This has raised a strong dependence of the rail networks on the local suppliers. Furthermore in most cases this carry out an incompatibility of these networks with the networks of neighbouring countries. To illustrate this situation it is only necessary to remember the different gauges in national networks (1,668 mm in the Iberian Peninsula, 1,520 in Russia, Finland, Baltic republics, 1,435 mm in the other European countries) to which must be added the numerous narrow gauges regional and urban networks. Another good example is the different supply voltages: 1,500 V dc, 3,000 V dc, 25 kV 50 Hz, 15 kV 16 2/3 Hz, which should add the 625 V dc, 750 V dc, 1,200 V cc, used in trams and regional rail systems. In the field of railway signalling, more than six different and incompatible systems exit. As we show in this document there are hundreds of other parameters that are different from one network to another: the height of the overhead line, the height of the platforms, the gauges an so on and so forth. The lack of interoperability, affects decisively to the creation of a European single market in rail transport for both: goods and passengers, which prevents private (or public) rail undertakings to give trans-national services and create a single market. The thesis focuses on the study of the directives relate to the interoperability and railway safety, and the technical specifications for interoperability (TSI). It leaves for future analysis the detailed studies European standards being developed for the technical harmonization of each subsystem parts. According to the author when the concept of interoperability was lunched in 1996, probably it was thought that the technical harmonization would be much easier. However, when it was analyzed in depth it was found a large number of discrepancies between the technical characteristics of each network raised. These parameters such as width and height of the pantographs, the stresses of the overhead contact wires, the length of the neutral zones, the height of platforms, the different kinematic and dynamic gauges and a long list of different parameters, made it impossible, in practice, the movement of trains across borders in a generalized manner in a short term. Finally it was recognized the fact that, for achieving real harmonized lines, it would be necessary to invest a huge amount of money not justify by the cost-benefit analyzes. The Thesis concludes that is necessary to put in force more strong Technical Specifications of Interoperability that leave less degree of freedom to the Member states: determining a single objective parameter value, trying to reduce the permanent specific cases and solving and reducing the list of open points. / El propósito de esta tesis es analizar el desarrollo de la interoperabilidad y seguridad ferroviaria en Europa en el periodo comprendido entre 1991-2011. La intención es evaluar cuál ha sido el proceso legislativo a nivel de la UE durante los últimos 20 años. Este análisis tratará de determinar si ha sido establecido desde una base suficientemente sólida para obtener una Red Ferroviaria Trans-Europea dentro de un periodo razonable, con uniformidad de instalaciones de seguridad. El segundo aspecto sería determinar aquellos puntos que deben ser corregidos o mejorados, o sencillamente re-examinados para acelerar el proceso de integración. Un aspecto común a las redes ferroviarias de los países europeos es su fuerte énfasis nacional en lo que respecta a normas de circulación ferroviaria y reglamentación técnica. Esta realidad conduce a la creación e implementación de productos específicos por parte de la industrial nacional. Esto ha llevado a una fuerte dependencia de las redes ferroviarias de suministradores locales. Asimismo, en la mayoría de los casos, esto lleva a la incompatibilidad de estas redes con las redes de países vecinos. Para ilustrar esta situación, solamente es necesario recordar los distintos anchos de vía en redes nacionales (1.668 mm en la península ibérica, 1.520 en Rusia, Finlandia y las repúblicas del Báltico, 1.435 mm en otros países europeos) al que habría que añadir las numerosas redes de vías de ancho estrecho regionales y urbanas. Otro buen ejemplo serían los distintos suministros de tensión: 1.500 V dc, 3.000 V dc, 25 kV 50 Hz, 15 kV 2/3 Hz, al que habría que añadir las de 625 V dc, 750 V dc, 1.200 V cc, utilizados en tranvías y redes de trenes regionales. En el ámbito de la señalización ferroviaria, existen más de seis sistemas distintos e incompatibles. Tal y como demostramos en este documento, hay cientos de parámetros distintos que difieren de una red a otra: la altura de la línea suspendida, la altura de andenes, los anchos, etc, etc. La falta de interoperabilidad afecta decisivamente a la creación de un mercado común europeo de transporte ferroviario para tanto mercancías como pasajeros, lo cual impide que empresas privadas (o públicas) ferroviarias puedan ofrecer servicios transnacionales y crear un solo mercado. Esta tesis se enfoca en el estudio de la reglamentación relacionada con la interoperabilidad y seguridad ferroviaria, y las especificaciones técnicas para la interoperabilidad (TSI). Deja para análisis futuros el estudio detallado de los estándares europeos bajo desarrollo para la armonización técnica de cada parte de subsistema. Según el autor, cuando el concepto de la interoperabilidad fue lanzada en 1996, probablemente se pensara que la armonización técnica sería mucho más sencilla. Sin embargo, al analizarlo en detalle se descubrió que aparecían un amplio número de discrepancias entras las características de cada red. Estos parámetros, como el ancho y alto de los pantógrafos, las tensiones de los hilos de contacto suspendidos, la longitud de zonas neutras, el alto de andenes, las diferentes propiedades cinemáticas y el ancho dinámico y una amplia lista de distintos parámetros hacían imposible en la práctica la circulación de trenes más allá de sus fronteras de forma generalizada a corto plazo. Por fin se reconoció el hecho de que para conseguir líneas verdaderamente armonizadas sería necesario invertir una enorme cantidad de dinero que no era justificable en los análisis de coste-beneficio. La tesis concluye que es necesario poner en vigencia especificaciones técnicas de interoperabilidad más fuertes que dejen menos libertad a los países miembros: determinar un solo valor de parámetro objetivo, y tratar de reducir los casos específicos permanentes y resolver y reducir el número de puntos abiertos.

With the distinguished natural and cultural tourism resources, Tibet is undoubtedly a desirable travel destination both domestically and internationally. With the newly opened Qinghai-Tibet railway to Lhasa in July 2006, Tibet tourism development was boosted markedly due to the increased accessibility and affordability. This study evaluates the impacts of the increased accessibility achieved through the Qinghai-Tibet railway on tourist travel decisions for, and experiences in, Tibet from travelers’ perspectives. The relative importance of the train journey in comparison with the destination experience at Tibet is also examined. A destination choice framework is proposed based on a review of previous literature. It is applied in this study to understand tourists’ travel destination choice of Tibet. A questionnaire survey was designed as the major primary data collection method to collect travelers’ perceptions on the train journey and Tibet tourism. Conducted on the train to and from Lhasa of Tibet, a total of 187 questionnaires were collected, including 82 for the pre-visit sample and 105 for the post-visit sample. Important destination choice factors for Tibet are identified in this study. The findings also support the importance of the railway on tourists’ destination choice of Tibet and in the overall travel experience of Tibet. Expectations and satisfactions with the destination are also compared to indicate possibilities for further destination development in Tibet. This study improves the understanding of both the supply and demand sides of the tourism industry in Tibet. Both practical implications and academic implications are presented based on the major findings of this study. Contributions of this study and future research opportunities are discussed.

In this work the influence of Under Sleeper Pads on the dynamic forces on a railway track is investigated. A special interest is devoted to the effect of using Under Sleeper Pads in a railway track with changing vertical stiffness. The contact force between wheel and rail and the ballast contact forces are examined. For the investigation a finite element model with the length of thirty sleepers is created and calculations are performed with the software LS-DYNA. Three different cases of varying vertical track stiffness are studied: the transition from an embankment to a bridge, a randomly varying track stiffness along the railway track and hanging sleepers.
