steep tourist line that connects to the Bergen Line. The units were painted green and connected at each end of a train of six B3 passenger cars. From 2003, the first series was taken out of regular service, and units 2222, 2224 and 2225 were put into shunting service at Lodalen. Unit 2223 was transferred to the Norwegian Railway Museum, where it was put on display. Specifications The El 17 was built by the manufacturer Thyssen-Henschel of Germany. The locomotives have three-phase asynchronous motors with a continuous output power of , allowing a maximum speed of . The units receive power from a pantograph and are the first class of locomotive for NSB that has regenerative brakes. The electrical equipment was designed by the manufacturer BBC (German plant Mannheim) but built by the Norwegian manufacturer Norsk Elektrisk & Brown Boveri (NEBB). Each locomotive is equipped with four NEBB BQg 3855 motors, giving a Bo'Bo' wheel arrangement and a maximum tractive effort of on dry rails. The El 17 is an electric locomotive designed for intercity trains, but is also capable of hauling light freight trains. The body is welded as a self-containing construction. The roof (light alloy) sections can be removed, and the locomotives were the first Norwegian locomotives to have a center aisle in the machine room. The locomotives are long, have a wheel diameter of and weigh . The locomotives can run in multiple; by using a UIC 568 signalling cable, the locomotives do not need to be adjacent to each other in the train. the El 17 has the unique pointed front that was first used on the El 16, and is also found on the Di 4 and Di 6 classes.
