This thesis addresses how the travellers participate in the production of space during train travels. It is based on a study of intervjues made in December 2013 with six members of the Swedish parliament who all are frequent travellers on the high speed train between Stockholm and Gothenburg. Using Henri Lefebvres theory of the production of space and contemporary theories on spending time during train travel combined with theories of how space and time are bound together as a timespace. The conclusion is that traveller do participate in the production of the train space by activities taking place based on the special conditions of the trainspace during the journey. Activities that forms the idea of lived space on the train as one of three spaces based on Lefebvres model of the triad of space. The study also identify the need of further research on the train space as a space of its own as we spend more and more time in this space.
