In July 2010, SBB Cargo placed the order for 30 Eem 923 hybrid locomotives from the Eem 2/2 vehicle series to cover traction requirements for shunting and freight train line services.
The locomotives operate under 15 kV/16.7 Hz and 25 kV/50 Hz and alternatively with a Diesel genset for the non-electrified last mile.
The customized multi-system traction solution excels in powerful traction, high reliability and energy-efficiency. Each ABB traction package contains one traction transformer and two Compact Converters BORDLINE® CC750. All components are highly compact and of lightweight design.
SBB benefit of a higher availability and lower operating and maintenance cost for the vehicles.
