The name means "the little Strøm", Strøm being the name of an old and large farm. Lillestrøm's history dates back to the times river powered sawmills came into use for the production of building materials. Later Lillestrøm got its own steam sawmill which laid the base for the development of the area which became the town. The area was, by and large, a moss covered swamp-like area, at the time considered almost uninhabitable. However, the almost non-existent property values were judged to be a fair exchange and so the workers started living and settling in the area around the sawmill, and Lillestrøm was born. On 1 January 1908 Lillestrøm became a municipality of its own, having been split from Skedsmo. At that time Lillestrøm municipality had a population of 4,351. On 1 January 1962 the two municipalities were reunited under the name Skedsmo. Before the merger Lillestrøm municipality had a population of 10,840. In 1997, Skedsmo municipal council declared Lillestrøm to be a town in its own right. The event is commemorated in an annual 4-day street fair, which includes music by high-profile Norwegian artists on several outdoor stages, food stalls, retail business exhibitions, and thrill rides. The whole thing is held in Lillestrøm's main thoroughfare and its connecting streets, which are closed to all vehicles for the duration. In 2002, Norway Trade Fairs moved from Skøyen to Lillestrøm.
Transport
Road
159 is a four-lane motorway connecting central Lillestrøm directly to Oslo. The European route E6 bypasses Lillestrøm a few kilometres to the west on its way from Oslo to the north of the country. National road 22, running from northwest to southeast, passes through the northern outskirts of the conurbation.
Rail
Lillestrøm is connected to Oslo by two separate railway lines. The Trunk Line runs to Oslo via the Grorud valley and is used mostly by commuter trains calling at all stations, as well as freight trains. Non-stop commuter trains, airport express trains, and long-distance expresses use the high-speed Gardermoen Line, which runs mostly in tunnel to Oslo. The Trunk Line north of Lillestrøm carries frequent local passenger trains as far as Dal as well as freight trains to Eidsvoll, Lillehammer, and Trondheim. The Gardermoen Line is used by airport express trains, regional trains to Eidsvoll and Lillehammer, and long-distance passenger services to Trondheim. Running north-east from Lillestrøm, the Kongsvinger Line conveys hourly local trains to Kongsvinger as well as a number of longer-distance trains, passenger and freight, to and from Sweden.
Air
, a village north of the town of Lillestrøm, is the site of Kjeller Airfield, founded in 1912, which has the closest operational runway to Oslo city centre. However, this is overshadowed by the much larger international airport at Gardermoen, which is further north but just 12 minutes away from Lillestrøm railway station by high-speed rail.
Facilities in Lillestrøm include hotels, Norway trade fairs, a brand new cinema, a mall, Lillestrøm torv, restaurants, a high speed commuter train that reaches both Oslo and Gardermoen airport, a community cultural house, and a community outdoor swimming pool complex. At Kjeller, just outside the city, there is a military airport and several research institutes.
