The DB BR145 is a Bo'Bo' mainline electric locomotives built by Adtranz primarily for the Deutsche Bahn at the end of the 1990s. The BR145 is primarily a freight locomotive but was also used for passenger operations.

The AdTranz DB BR145 derives from the prototype locomotive 128 001 (also known as 12X) that was built by AEG and Henschel; like competitor Krauss-Maffei's 127 001, it uses asynchronous electric motors to drive the locomotive: based on experiences gained from DB Class 120.
