The class 146 is a 160 km/h locomotive series developed for regional Trains, which is derived from Bombardier's "Traxx" family and therefore technically related to the freight locomotives of the 145 and 185 series. 130 units have been built since 2001, since the end of 2015 locomotives of the 146 series are also in long-distance service with InterCity double-deck coaches (called "IC2" by the DB).
