The vehicle known as Ee 922 features dual-frequency and a power rating of 750kW. It can pull a 700t train up a ramp with a gradient of 0.6%. The vehicle is also the first electrical locomotive to be manufactured completely by Stadler Winterthur.
The remaining 20 vehicles, under the SFr40m ($39m) contract, are expected to be delivered by the end of 2010. The vehicles will replace SBB’s 40-year-old existing fleet of Ee 3/3 series vehicles at seven stations.
