In July 1998, Adtranz received a follow-on order for 400 more locomotives for medium-weight freight trains, the DBAG Class 185. The double voltage Class 185 was meant for international operation, and was also dubbed "Europalok". The basic concept of the running gear, the axle hung motors, the ester cooled inverters and transformer was maintained from the Class 145. In addition to the electronics for double voltage operation, modifications included the provision for the installation of the full variety of train protection systems in use in Europe, and the lowering of the roof by 105 mm to fit the vehicle in the international UIC 505-1 loading gauge.
