New, stricter safety specifications forced Bombardier to increase the crash safety of the TRAXX 1 locomotive body. As a result, the TRAXX 2 locomotives that have been manufactured since 2005 boast a vertical front section at the bottom as well as altered shunting treads on the fronts. Many components inside the vehicle were also simplified and standardised in order to be able to respond to customer desires in a more flexible manner whilst also reducing in-house production work. For instance, the time for the final assembly of a TRAXX locomotive has been reduced to a maximum of two weeks. In order to also be able to distinguish them in terms of their fleet number, the locomotives have been issued with the subclass numbers 185.2 and 146.2 to 146.5 at Deutsche Bahn AG. In the meantime, Bombardier has globally produced over 1500 units of this highly successful TRAXX family.
