This report describes a project intended partly to survey the need for multidisciplinary competence in the fieldof light rail transport and partly to determine whether there is a possibility and a need for expanding light railtraffic in Sweden as a complement to other forms of public transport. The results indicate that:

• There is growing interest in light rail transport in Sweden. Discussions are in progress in several Swedishcities concerning the possibility of developing existing light rail transport systems and/or reintroducing andexpanding present tram systems.
• Although knowledge is available, it is spread among several actors and there is a need for complementaryresearch.
• It is desirable for research and development in light rail transport to be better coordinated and to have amultidisciplinary basis with the focus on attractiveness and acceptance, socioeconomic aspects, safety aspects,and infrastructure and vehicles.

The work has been carried out in the form of a number of sub-projects. The material for the report consistsboth of a literature survey and of a number of interviews with actors connected with light rail transport.
