Reduction of the environmetal impact
From the start, Siemens studied the eco-balance of the entire vehicle for Oslo and conducted a lot of basic research. With an unexpected result: For operation in Oslo, weight is not only the most significant lever to save energy. But as well the heating systems inside the cabin and the isolation of the carbodies. Thus, the energy demand can already be optimized during the design of the commuter train.
Train optimization with respect to
Energy-efficient air conditioning
High recycling rate
Energy recovery during braking
Lightweight railcar construction
Realization time from September 2003 to March 2018
