Swedish "Green Train" project supported by Bombardier shows
faster, less costly and more energy-efficient trains are
possible on existing track
New generation trains running on existing track can easily
combine higher speeds, lower energy consumption, reduced
noise and lower costs. These are the findings reported by
Swedish researchers in Stockholm today after concluding a
four-year project, with Bombardier Transportation as one of
three major partners.
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 travellers 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 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 emphasized that the development programme was not a
finished train model but should rather be seen as a
smorgasbord of proposals and technical innovations adapted
to Nordic conditions.
The concept offers operators and infrastructure managers
advantages such as flexible train length, reliability and
accessibility even in the demanding Nordic climate. It also
reduces costs to ensure profitability in competitive
markets, increases track-friendliness with less wear to
track and wheels, enables high speeds on standard tracks
and lowers noise levels compared to the current
generation of trains. Aerodynamic design and more efficient
motors which generate electricity when braking enable the
Green Train to reduce power consumption by 30 to 35 per
cent. Thanks to the Nordic track profiles, trains can be
designed with greater width than existing trains, enabling
more passenger space while maintaining comfort which means
higher operational economy and, potentially, lower ticket
prices.
"Through this cooperation between several partners, we have
achieved results much quicker and with significantly higher
quality and innovative scope than in conventional
development projects," said Henrik Tengstrand, Director,
Mainline and Metros Vehicle Performance Engineering and
Bombardier's Project Director for Gröna Tåget. The Gröna
Tåget technology has been tested in trial runs over a total
of 500,000 km in all weather conditions since 2005. Its
development has involved a large part of the Swedish rail
sector, including manufacturers, infrastructure companies,
universities, train operators and research institutes. The
findings will be made available to all rail industry
companies and train manufacturers.
