environmentally sound
Costs, reduced energy consumption and the use of natural and recyclable
materials offer benefits for operators and the environment alike. The
experience gained with the Oslo metro project, which has a certified
97.5% recycling rate, is an integral component of the platform concept.
The lightweight aluminium carriage structure, the new demand-controlled
air conditioning and the weight-optimised chassis reduce energy
consumption. The electrodynamic braking system slows the vehicle to a
standstill and thus reduces noise and fine particle emissions. The
optional driver assistance system and the possibility of driverless
operation, as a unique feature also in combination with conventional
operation, guarantee the highest level of energy efficiency. The
Syntegra system, available as an alternative to conventional drive
technology, is particularly efficient, reducing energy consumption by as
much as 30% and lowering maintenance costs by up to 15%. The torsionally
yielding frame also reduces rail wear. Further advantages include the
lower interior noise level and the non-use of transmission oil, thereby
increasing passenger comfort and keeping the rails clean.
