The class Ge 4/4 III electric locomotives are the latest locomotives on the RhB and they can be seen pulling all types of trains. With a performance of 2,400 kilowatts / 3,217 horsepower and a maximum speed of 100 km/h / 63 mph, they meet all the requirements present for use on a mountain railroad. In recent years, the RhB began to modernize these locomotives delivered starting in the mid-Nineties. The electronics were updated and thereby brought up to the current standard and the locomotives were equipped with modern LED headlights. The horns originally installed have been replaced by a compressed air whistle. Updated in this way, these locomotives are good for service for another 20 to 25 years.
