In the nineties, the Austrian Federal Railways (Österreichische Bundesbahnen or ÖBB) was in need of new electric locomotives to replace the older models. The new locomotives were built to drive high-speed trains and heavy freighter trains. The first Taurus (the official nickname of the Siemens ES64U2) that was built for the ÖBB was introduced on the 12th of July 1999 by Krauss-Maffei in Munich Allach. From January 2000 onwards these locomotives were in service in Austria. The Austrian authorities refused the purchase of the DB Baureihe 152 in 2001 because the railway network in the country was overcrowded. For this reason, the Deutsche Bahn bought 25 of the Baureihe 182 locomotives.
