Abstract
In Sweden, the tramway was introduced in the late 19th century as horse tramways. Entrepreneurs around the country saw advantages of the new mean of transport which, due to low frictional resistance could transport a large amount of passengers with low traction force. In the beginning of the 20th century the horses were replaced by electric motors and the tramway spread to more cities. The entry of cars and buses in the 30's meant that the tramway was no longer considered necessary. After the shift to right-hand traffic in 1967 the tramway only survived in two Swedish cities. In recent decades, the tramway is coming back, because of the electric motors and their good environmental attributes. Strong arguments are also the tramways’ high... (More)
In Sweden, the tramway was introduced in the late 19th century as horse tramways. Entrepreneurs around the country saw advantages of the new mean of transport which, due to low frictional resistance could transport a large amount of passengers with low traction force. In the beginning of the 20th century the horses were replaced by electric motors and the tramway spread to more cities. The entry of cars and buses in the 30's meant that the tramway was no longer considered necessary. After the shift to right-hand traffic in 1967 the tramway only survived in two Swedish cities. In recent decades, the tramway is coming back, because of the electric motors and their good environmental attributes. Strong arguments are also the tramways’ high capacity and its structure-forming attributes in urban areas. The purpose of this report is to summarize the different types of track constructions and construction methods for tramways used. This is accomplished by a literature review and inventories of four different Swedish tramway projects: Tvärbanan - Solnagrenen and the Spårväg City in Stockholm, The Kringen project in Gothenburg and the tramway expansion to Navestad in Norrköping. The inventories were conducted by means of drawing analyses and interviews with key informants in the projects and experts of tramway. The construction methods used are divided into building on location or as prefabricated track. Track construction can be divided into three groups depending on the material a potential sleeper rests on: macadam track, asphalt track and concrete track. Another important definition is how the tramway environment looks like. These we define as: track on its own embankment, separate track in the street and track in the street with mixed traffic. Tvärbanan - Solnagrenen runs through several tramway environments, tunnels and bridges. Most parts are macadam track on its own embankment but also asphalt track is used on the part in Sundbyberg and Solna Business Park. Spårväg City, in the center of Stockholm, is partly built with prefabricated concrete segments of the type embedded rail. Remaining parts are reconditioned asphalt track from the old Djurgårdslinjen. The Kringen project in Gothenburg’s first and last part is Skånegatan and Skeppsbron. Skånegatan is constructed with macadam track and a surface coating of grass. Skeppsbron on the other hand will be completed in 2015 and will be built with concrete track with surface coating of concrete, asphalt and paving stones. The tramway expansion to Navestad in Norrköping was built as separate track in the street and as track on its own embankment. Overall the track was constructed with macadam track with a surface layer of grass. The literature review and inventory result in a summary of parameters and values. These are evaluated and motives for the track construction and construction methods used are stated. The asphalt track is used mainly because of traditional motives. Macadam track is used of simplicity and the close relationship to the means of building railway. Concrete track has good sustainability and can be prefabricated to reduce construction time. Surface coating of asphalt, concrete and paving stones are all drivable coatings with different advantages and disadvantages. Grass is a popular and attractive coating to separate the track area. The choice of construction methods and track constructions differs and depends on the conditions on site. Concrete structures for tramways are popular in France and looks to become increasingly more common in Sweden. The previously popular asphalt track seems to disappear rather than increasing. Costs for the different track constructions and construction methods are difficult to estimate and a suggestion for future studies is to compare costs between different track constructions and construction methods.
