Utbredning av markvibrationer och stomljud från järnväg : Undersökning och anpassning av beräkningsmodell

The problems with train-induced vibrations are increasing with heavier and faster trains. Therefore the work with propagating vibrations is of outmost importance, and that is what this thesis relates to.To get a sensible idea of the propagation, calculation models are often used. Propagation calculation models takes into account factors such as distance to the railway, the ground material and the velocity and weight of the train. This work is mainly about finding suitable existing models and, if necessary, adjust them to be more useful with modern trains and Railways.The report contains the work of adjusting one such model and does, despite the fully functional adjusted model, describe how much more there can be done within this topic. Finally, a few tips about specific areas that preferably should be studied to get even further knowledge about the troublesome problems from Railways..

Regeringens transportinfrastruktursatsningar : En studie av tågtrafikens utrymme i regeringsanslagen för transportsektorn

In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for operation and maintenance of the Railways are much higher then in the last government's bill. Furthermore the current founding of investment in Railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.

När tågen slutat gå : förvandling av övergiven räls till publikt promenad- och parkstråk

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of Railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned Railways area in Stockholm: Eriksdal railway area.

Erfarenhetsåterföring i praktiken : En studie vid Jernhusen AB

This examination has been made in cooperation with Jernhusen which is an estate company owned by the government, with estates along the Railways in Sweden. This assignment is to help Jernhusens business area Projektfastigheter with their experience feedback, which is to-day almost absent. Business area Projektfastigheter has the task of supporting Jernhusens three other business areas with skills and resources for the estate projects that Jernhusen runs. Jernhusen must become stronger with the collecting of experiences and as a business because of the liberalization of the Railways, which leads to a more competitive market. A tool for this is successful experience feedback.The concept of experience feedback is to gain experience across a variety of cases, where individuals and/or groups can chose situations with relevant similarities and differences with current case.

ÄTA-arbeten på Trafikverket

?ÄTA-work? (Changes, Supplementary and Retiring works) is more or less common in all construction projects whether it is about houses, roads or Railways, in the planning stage, or in the construction stage. For the Swedish Transport Administration, which is the largest purchaser of infrastructure in Sweden, ÄTA-work is a hotter topic than ever.Economists and managers want to draw conclusions on the projects share ÄTA-work, while the project manager is concerned about whether it is possible to draw any conclusions at all as each project is unique in itself and has its own merits. There is a big variation in the amount of ÄTA-work in different geographic districts in the Swedish Transport Administration.This study shows that the Swedish Transport Administration does not have a unanimous approach regarding the management of ?ÄTA-work?.

Förutsättningar för drift och underhåll av det statliga vägnätet : - En fallstudie om entreprenadkontrakts utformning i driftområdena Åsele och Jokkmokk

This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the Railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.

Marknadsanalys av ett svenskt transportsystem med höghastighetsgodståg.

In Sweden plans to build high speed Railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed Railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these Railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.

Järnvägsstationer i Litauen 1861-2011 : Namngivare, namnbyten och språkbyten genom 150 år

The names of railway stations and halts along the earliest railway lines on Lithuanian territory have been studied, i.e. along those railway lines built between 1861 and 1873. Especially, attention has been drawn to names that are not obvious regarding the geographical location of the station or halt. Some 50 percent of the names are showing some kind of irregularity in this respect. Most common (about 30 examples) are stations or halts that are serving a population centre situated at some distance from the station, but still bearing the name of that population centre.

En klimatanpassad järnväg : Långsiktig planering av infrastruktur i ett föränderligt klimat

Global warming is going to affect our society in many ways. One can say that the problem we face has two different sides. One of those sides has received a lot of attention, namely how we can reduce our emissions of greenhouse gases. However, because of the climate system's inertia the climate will continue to evolve over a period, no matter how much we will cut back on emissions. Because of this, we have to start adapting our society to the climate changes that we cannot influence.

Kontaktförbindningar på räls : Undersökning av hur pinnlödning och borrning påverkar materialet i järnvägsräls

Vid dragprovning av lödningar framkom att i många fall är kopparledningen svagare än själva lödningen och brottet sker i kopparledningen eller i kabelskon. Undersökning av mikrostrukturerna visade att det bildas martensit i grundmaterialet i ett område under pinnlödningarna. Medelvärdet på martensitlinsens storlek beräknades till 10,69 mm i diameter och 0,73 mm i djup. På grund av att grundmaterialet påverkas bör pinnlödningar sättas minst 10 mm från varandra. Lödningar gjorda i -5°C visade inga tecken på försämrad kvalitet med avseende på lägre hållfasthet eller ökad martensitbildning.

Utsikt från höghastighetståg : om reseupplevelsens krav på landskapet

As we travel more and more by train it becomes increasingly important that the time we spend traveling, is of great quality. This has been the foundation of this master thesis and has shaped the outcome of it. The traveling experience, that is, the experience of the landscape that flashes by outside the train window, is an important aspect in railway planning and an aspect that should be taken into greater consideration. The purpose of this master thesis has been to examine how to compose or improve the travel experience for an already planned high speed railway and how the travel experience can be combined with other aspects, which have claims on the landscape. This thesis is based on a literature study and a case study of Ostlänken. The work describes Ostlänken, a planned high speed railway in Sweden between Järna and Linköping, with top speeds at 300-320 kilometers per hour.

Helandet av Stockholms sår : En analys av projektet Västra City

Over the years, what people have considered as the center of Stockholm City has gone from the medieval Stortorget in Old Town to the contemporary Sergels Torg. But more recently it has become unclear how the area really works. It is difficult to say where the actual central part of Stockholm lies, because while the Central Station is where the majority of people arrive into town, it is not necessarily close to Sergelstorg (considered the center of town) or other attractive commercial areas. There's also another issue with where the center of Stockholm is located. The Railways and roads running along Klarabergs Viaduct acts as a divide between the areas of Kungsholmen and Norrmalm; these rails, roads and water separate the two areas from each other. In response to this problem of area division, a plan is being made to construct a new district near the center to mend the gap between the districts. The idea is that the center of Stockholm city will become more lively and attractive. The plan includes building new housing, commercial areas and a larger terrace called Mälarterrassen. In addition, improved mobility within the area is being planned by having better public transportation lines like City banan and tram named Spårväg City construction, as well as more pedestrian areas shall make the area become a district to thrive in.How the area will actually operate in the future is still unclear and many questions still exist about how the area will be able to compete and, above all, integrate with the other districts. The parts considered to be most important for the area is the scale of residential property and an attractive area that keeps people in the area and to encourages them to pass through the area. Perhaps the best solution would be to have something special planned in this area that can attract people in the community ? a city park, for example?.

Kisa Stationsamhälle : från kyrkoby till municipalsamhälle 1895-1905

The current field of research concerning the impact of railroads in Sweden beside from the State main-line network is relatively narrow. Including cultural impact to the area narrows the results even further. The purpose of this study is to open the field even more into the local societies and to what extent the impact of the introduction of railroad might have had on smaller county villages. Sweden holds a unique position concerning ?station towns? or ?Railways towns? in terms of railway policy and the industrial development in towns that were affected by the railway, as the affected towns continued development were based on a hybrid between direct democracy and adaptations of city-law policies.This study takes place in Kisa, a small town in southern Östergötland that during the beginning of the 20th century turned into a municipal community due to the building of Östra centralbanan (roughly translated Eastern central-line).
