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.
