The class is so named under the Swiss locomotive and railcar classification system. According to that system, Ge 3/3 denotes a narrow gauge electric adhesion locomotive with a total of three axles, all of which are drive axles. There are only two locomotives in the Ge 3/3 class, and they are numbered 214 and 215.
Delivered by Robert Aebi (Raco) and Brown, Boveri & Cie (BBC), the Ge 3/3s feature some componentry — e.g., traction motor, compressor and vacuum pump — that are the same as the corresponding components in the second series locomotives of the Rhaetian Railway Ge 4/4 II class.
The orange liveried Ge 3/3 locomotives are used at major Rhaetian Railway stations: no 214 in Samedan and no 215 in Chur.
