The Gröna Tåget (”Green Train”) research project is a collection of ideas, proposals, and technical solutions aimed at making long-distance and fast regional services more attractive to travelers and operators. Gröna Tåget is a fast electric tilting train —based on the BOMBARDIER REGINA vehicle— that not only maintains higher speeds than conventional trains on sections with curves but also 300 km/h (186 mph) or more on dedicated high speed lines.
The project was conducted in close cooperation between the Swedish Transport Administration, Bombardier, the Royal Institute of Technology in Stockholm, and several other partners.
In the report, the project team noted that the concept train had set a Swedish speed record of 303 km/h. But it noted that the development program was not a finished train model but should rather be seen as a smorgasbord of proposals and technical innovations adapted to Nordic conditions.
