context_page_description: A/S Kristiania Elektriske Sporvei or KES, nicknamed the Blue Tramway, was a company which operated part of the Oslo Tramway between 1894 and 1924. It built a network of four lines in Western Oslo, the Briskeby Line and the Frogner Line which ran to Majorstuen, and two other consecutive lines, the Skøyen Line and the Lilleaker Line. These all connected to a common line through the city center which terminated at Jernbanetorget.
  KES was established as the second tram operator in Oslo. When it commenced services it was the first electric tramway in Scandinavia. It originally opened the Briskeby Line and the Skøyen Line to Skillebekk using a fleet of Class A trams. Later the company also ordered Class U and Class SS trams, for a total 78 motor cars and 66 trailers. Skøyen was reached in 1903. The first part of the Frogner Line opened in 1902, and it was completed in 1914. The Lilleaker Line was built to Lilleaker in 1919. KES and its competitor, Kristiania Sporveisselskab were both taken over by Oslo Municipality in May 1924 and became Oslo Sporveier. The take-over did not include the Lilleaker Line and this part of the operation continued as Bærumsbanen.
context_section_description: The company bought a total 78 motor cars and 66 trailers; 20 of the motorized vehicles were later converted to trailers. The deliveries were from various manufacturers, most of which were German. The sole Norwegian body manufacturer was Skabo. The trams were of three generations, each with their own class designation. Many of the trams were of the same class as those delivered to KSS. KES's trams were painted blue, hence giving rise to their nickname, the "Blue Tramway".
  The first class of trams, Class A, were manufactured by Allgemeine Elektrizitäts Gesellschaft (AEG) and P. Herbrand & Cie., both of Germany. The undercarriages were built by Bergische Stahlindustri. They featured open platform bays and a cabin. Twenty units were built, with nearly the same specifications. The trams were 6.5 meters (21 ft) long and 2.0 meters (6 ft 7 in) wide. They weighed 6 tonnes (5.9 long tons; 6.6 short tons) and were equipped with two NB80 motors with a combined effect of 12 kilowatts (16 hp). The exception was three units, no. 118 through 120, which had more powerful VBN120 motors, with a combined 36 kilowatts (48 hp). They had seating for sixteen and standing room for twelve. The company also had thirty-two similar trailer units built by Herbrand. One of the trams, no. 117, was a prototype built by Skabo with motors from Norsk Elektrisk & Brown Boveri.
  Twenty-four Class U trams were delivered between 1899 and 1906. The electrical components were built by Union-Elektricitäts-Gesellschaft and the bodies by Falkenried and Skabo. The trams had two GE52 motors with a combined power output of 36 kilowatts (48 hp) and had a total weight of 10.2 tonnes (10.0 long tons; 11.2 short tons). They were 7.8 meters (26 ft) long and were built with open platform bays. Each unit had capacity for twenty seated and fourteen standing passengers. Two units were in 1924 rebuilt to create an articulated tram. However, it proved prone to derailment in poorly banked S-curves and was never put into revenue service.
  KES took delivery of thirty-four Class SS motorized trams and twenty-two trailers between 1909 and 1914. They had electrical components from Siemens-Schukertwerke and were variously built by Herbrand, Falkenried and Skabo. Their main innovation was that the wheelbase was increased from 180 to 360 centimeters (71 to 142 in), allowing for a lengthening of the body. The first eleven were 9.69 meters (31.8 ft) long, while the rest were 11.47 meters (37.6 ft) long. The first eight units had two D72v motors, giving a combined power output of 72 kilowatts (97 hp). Later units had a power output of 84 kilowatts (113 hp).
  The second delivered unit, no. 102, has been preserved by the Norwegian Museum of Science and Technology. Two SS motor units, no. 307 from 1913 and no. 322 from 1918, and one trailer, no. 347, have been preserved by the Oslo Tramway Museum.
