The Ee 3/3IV, the fourth iteration of the Ee 3/3 series, is a class of ten shunting locomotives specially designed for use as pilots at border stations. The complicated equipment needed for four different electrical systems required a higher and wider body in front of and behind the cab and a reduction in power. Nevertheless, thanks to a modern crank drive, a maximum speed of 60 km/h can be attained.

History

The Ee 3/3IV are used in French and Italian border stations, mostly at Geneva, on similar duty to the previous versions. All locomotives were equipped with a multiple drive in 1994, similar to the Ee 3/3II. During the upgrade the locomotives received new service numbers (Ee 934).

Due to their ability to run on 1,500 V DC system, they were occasionally used to haul passenger trains between La Plaine and Geneva when the SBB BDe 4/4 II were being repaired.
