Bombardier has supplied 50 TRAXX F140 AC locomotives to Swiss rail operator SBB Cargo to expand and modernise their fleet in the last 15 years. The order included 35 AC1 locomotives, built to a conventional BR185 design and 15 locomotives, delivered from 2004 onwards, featuring a new carbody, enhanced to the latest standards with increased crash energy absorption. Amongst other innovative technologies, the locomotives have:
- Advanced propulsion cooling systems;
- Regenerative braking, enabling energy from braking the train to be fed back into the overhead lines;
- To ensure passenger safety and in compliance with Swiss regulations, driver cabs are equipped with rear view cameras.
