context_page_description: The Rhaetian Railway Ge 4/4 ᴵ is a class of metre gauge Bo′Bo′ electric locomotives operated by the Rhaetian Railway, which is the main railway network in the Canton of Graubünden, Switzerland.
  The class is so named because it was the first class of locomotives of the Swiss locomotive and railcar classification type Ge 4/4 to be acquired by the Rhaetian Railway. According to that type designation, Ge 4/4 denotes a narrow gauge electric adhesion locomotive with a total of four axles, all of which are drive axles.
  The 10 machines in the Ge 4/4 ᴵ class were also the first RhB electric locomotives without rod drive.
context_section_description: The Ge 4/4 ᴵ class locomotives presently have a top speed of 80 kilometres per hour (50 mph) (originally 75 kilometres per hour or 47 miles per hour) and a power output of 1,184 kilowatts (1,588 hp).  They now weigh 48 tonnes (47 long tons; 53 short tons) (originally 47 tonnes or 46 long tons or 52 short tons) and are 12,100 millimetres (39 ft 8 in) long.
  Beginning in 1997, the Ge 4/4 ᴵ class's old diamond-shaped pantographs were replaced by new single-arm pantographs, to enable deployment of the class on the Chur-Arosa line, which at that time was having its electrification system changed.
  The names of the 10 locomotives in the class commemorate the names of certain valleys, mountains and mountain ranges in Graubünden.  The names are located high on the left and right sides of the locomotives, in white script on a red background.  The service numbers 601–610 are on both cab ends, and also on the lower sides.
