Alstom TRAXX локомотивтері: түрлері мен ерекшеліктері

Family of locomotives manufactured by Alstom, originally by Bombardier

The TRAXX F140 AC operates on AC overhead lines. 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 area of the Swiss Federal Railways, SBB Cargo (SBB Re482), and 20 units for Swiss private railway BLS AG (BLS Re485). The Swiss locomotives differ from the German versions in details such as pantographs (2 more, with smaller contacts for running under Swiss catenary (not because of tunnels)) and Switzerland specific safety systems in addition to the German systems.

In Luxembourg CFL operates 20 locomotives.

The TRAXX P160 AC is the passenger version of this class, with a correspondingly higher top speed of 160 km/h. A lower unsprung mass was achieved by using hollow shaft final drives instead of the axle hung motor arrangement of the 140 km/h maximum speed versions. The bogies and drive unit are the same as used in the DBAG Class 146.0.

The first AC member of the TRAXX 2 family, which featured carbodies with improved crashworthiness and water cooled IGBT based inverters, was the demonstrator loco 185 561, delivered in May 2004. It was produced ahead of the main tranche of TRAXX F140 AC2 locomotives for homologation of the class in Germany. Another demonstrator TRAXX F140 AC2, 185 568 was used for tests on the then new HSL Zuid in 2006. Subsequently, it was used for tests of the ETCS system. Both demonstrator locomotives were eventually sold to private operators for normal use. The remaining 200 of the 400 Class 185 freight locomotives ordered for DB Cargo were to be of this type, and the new versions were given the subclass designation DBAG Class 185.2. Since this large order represented the main body of production at Bombardier's Kassel plant, any further private orders for the AC locomotives would be included into the F140AC2 production line thus the original F140 AC type effectively ceased production when the production of DB Cargo's (by then renamed Railion) Class 185.2 began. The locomotives operated by SBB Cargo are designated Re482.2.

Alongside the F140 AC2 locomotives, the passenger versions received the same improvements. DB Regio received 47 units between 2005 and 2006; as with the freight version the '.2' subclass was used to distinguish these new versions the Deutsche Bahn locomotives being classified as Class 146.2, following on from the Class 146. A number of smaller orders have been received, including more units for the metronom railway procured via LNVG. DB Fernverkehr, the German Railways branch which operates Intercity services, ordered 27 more Class 146.2 locos on 12 January 2011. The locos will start service in December 2013.

In 2012, Bombardier presented the third generation TRAXX. Its exterior is different from previous generations. DB Fernverkehr took delivery of its first TRAXX AC3 locomotives (Class 147.5) in 2018 in a batch of 17. According to a January 2020 IRJ article, DB Fernverkehr refused to take delivery of the second batch of TRAXX AC3 locomotives in 2019 due to software related issues. The rail transport company uses its TRAXX AC3 locomotives for its IC2 trains (as seen in the photograph on the right). Models operated by DB Regio are classed as DB Class 147. The TRAXX AC3 has an installed power of 5.6 MW, and a top speed of 160 km/h.
