In July 2010, SBB Cargo ordered 30 BUTLER Eem 923 dual-power locomotives from Stadler for traction requirements for shunt-

ing and light cargo duties. The dual-power vehicle is a compact locomotive which can be operated at 15 kV/16.7 Hz or 25 kV/50 Hz

when connected to the overhead contact line. It can also be operated independent of the overhead contact line for the «last mile»

without any loss in train performance. With an output of 1500 kW, a maximum speed of 120 km/h and the option of multiple

unit train control for up to four locomotives, the Eem 923 is suitable both for line service and shunting. It is primarily operated

with an overhead contact line. This makes it very economical in terms of consumption. In addition, the Eem 923 requires little

maintenance and promises high levels of availability and longevity.
