The class is so named because it was the second class of locomotives of the Swiss locomotive and railcar classification type Ge 6/6 to be acquired by the Rhaetian Railway. According to that type designation, Ge 6/6 denotes a narrow gauge electric adhesion locomotive with a total of six axles, all of which are drive axles.
In the 1950s, traffic on the Rhaetian Railway grew so strongly that the existing Ge 6/6 Crocodiles and the Ge 4/4 I Bo-Bo locomotives were no longer sufficient. Construction of the Bergell power station, begun in 1958 by the Elektrizitätswerk der Stadt Zürich, required the transfer of up to 1,000 tonnes (980 long tons; 1,100 short tons) of cement per day from the Untervaz to the Engadin. For that task, the Rhaetian Railway required a locomotive that could haul a load of 250 tonnes (250 long tons; 280 short tons) on the 3.5% gradients of the Albula Railway.
The two locomotives of the first production run (numbers 701 and 702) were delivered by the manufacturers Schweizerische Lokomotiv- und Maschinenfabrik (SLM), Brown, Boveri & Cie (BBC) and Maschinenfabrik Oerlikon (MFO) at a price of 230,000 Swiss francs each. The remaining locomotives in the class (numbers 703 to 707, each placed in service in 1965) were each 200,000 francs more expensive.
The Ge 6/6 II locomotives have a top speed of 80 kilometres per hour (50 mph), weigh 65 tonnes (64 long tons; 72 short tons), and develop 1,776 kilowatts (2,382 hp) at 46 kilometres per hour (29 mph). The maximum towing load is 205 tonnes (202 long tons; 226 short tons) at a gradient of 4.5%, and 280 tonnes (280 long tons; 310 short tons) at a 3.5% gradient.
The first two locomotives were fitted with communication doors on the cab fronts. These were welded up in 1968–69, but the complete assimilation of the first two locos with the second series (which have two instead of three cab end windows) occurred only towards the end of the 1980s. In 1985 the Rhaetian Railway began reliverying the class from green to red, and in 1998 the original diamond shaped pantographs were replaced with modern single arm pantographs.
The Ge 6/6 II today
After completion of the Bergell power station, the 700s were used predominantly to haul fast passenger trains on the Albula Railway. Since these duties were taken over by the Ge 4/4 III class, which was placed in service in 1993, the Ge 6/6 II has been found mainly at the head of goods trains on the whole of the Rhaetian Railway's core network (apart from the Arosa line). However, the 700s can still be seen hauling some passenger trains.
Loco 701 carries the name of the Roman province of Raetia, which to this day has remained as a synonym for the Swiss province of Graubünden. Loco 702 bears the name Curia, which is the Latin name of the canton's capital city, Chur. The remaining locos, numbered 703–707, are named after major Graubünden municipalities, each situated at an end point of the core network. Adjacent to the name on every locomotive is the traffic number in white, along with the coat of arms of the applicable municipality (on loco 701, the Graubünden coat of arms).
