They can work under both the 15 kV/16.7 Hz and the 25 kV/50 Hz AC systems. As built they are configured for future ETCS / ERTMS train control and safety systems. The 200 units built between 2001 and 2003 for Deutsche Bahn were classified as DBAG Class 185, or DBAG Class 185.1 once production switched to the TRAXX F140 AC2 design. A further 57 units were built for various European leasing companies, and were classified in Germany as Class 185.5. Another 35 units were produced for the freight business
