We have previously developed the Framework for Strategic Sustainable Development (FSSD). It is based on robust boundary conditions for sustainable redesign. This supports sustainable development transitions that takes the whole civilization/biosphere system into account in a systematic way while ensuring sufficient access to money and other resources. We have applied the FSSD for regional sustainable development to develop goals for sustainable transports in the South of Sweden, plus roadmaps to get there. Building on this we have also made sustainability comparisons of future scenarios and transition pathways with and without Maglev systems in a Swedish and Scandinavian context. In this new study, we revisit the Swedish case while furthering the combined sustainability comparison model to improve our capacity to analyse Maglev systems anywhere in the world. We found that new Maglev systems have a generic ‘plus-side’ with aspects like higher speed and efficiency, lower energy use and maintenance costs, spatial advantages, etc. On the generic ‘minus-side’ we also found that existing rail-systems with supporting infrastructure have already been built which may speak in favour of upgrading it for traditional high speed trains rather than building a Maglev infrastructure from scratch. In Sweden, the societal land transport discourse has mainly revolved around whether highspeed trains should be developed on an already existing infrastructure for rail-traffic, one that is already plagued by difficulties to stay on time, with high maintenance costs to make already existing cargo traffic and various types of personal train transportation fit the same structure. We conclude that Sweden now needs a thorough sustainability cost/benefit evaluation where transport futures with and without highspeed trains and Maglev are objectively compared.
