SBB-CFF-FFS Eem 923


The SBB-CFF-FFS Eem 923 is a dual power version of the SBB-CFF-FFS Ee 922 electric shunting locomotive of Swiss Federal Railways. Thirty locomotives have been ordered from Stadler.

History

SBB has different shunting engines in use, which had reached a significant age around 2010. Maintenance became expensive, and these machines were from an ecological perspective no longer viable. SBB Cargo decided to order new dual power locomotives to use in the best way the electrified rails with only short sidings being without electric power.
SBB procured 30 machines in 2010 from Stadler Winterthur AG with an overall value of CHF 88million. The first machine was delivered in March 2012.

Specification

The wheel arrangement is Bo. It can run at up to 100 km/h on 15 kV or 25 kV electrified lines. The machine has a 360 kW diesel engine with generator for operation on non-electrified sidings.
