The Asker Line (Norwegian: Askerbanen) is a 9.5-kilometre (5.9 mi) railway line between Asker and Lysaker in Norway. The line runs along the same corridor as the Drammen Line, offering increased capacity, speed and regularity on the rail network west of Oslo. The first part opened in 2005, and in 2011 an extension opened from Sandvika to Lysaker. Original plans called for an extension to Skøyen, but from 2020, new planning is under way for an extension all the way to Oslo Central Station. Most of the railway is in tunnel and is dimensioned for 160 km/h (99 mph) running. The entire railway is electrified at 15 kV  16.7 Hz AC. The first section cost 3.7 billion kr, while the second is budgeted at NOK 2.7 billion. The purpose of the new line is to allow regional and express trains to run directly between Asker Station, Sandvika Station and Lysaker Station, without being slowed and delayed by commuter trains that make frequent stops at intermediate stations. The Asker Line will improve regularity, and capacity will increase from 12 to 26 trains per hour in each direction. Travel time from Asker to Skøyen Station will be reduced from 20 to 13 minutes. The line has received criticism for not being a true high-speed line, and for Lysaker Station not being in compliance with accessibility requirements. Similar parallel, high-speed lines have been or will be built northeast and southeast of Oslo. The line is built, owned and maintained by Bane NOR (previously the Norwegian National Rail Administration). At Sandvika, the line connects to the Drammen Line, which runs to Oslo Central Station in the east. At Asker, the line connects to the Spikkestad and Drammen Lines; the latter connects to the Sørland- and Vestfold Line at Drammen. The line is served by Vy with regional trains to Vestfold, Buskerud and Telemark, and the express trains along the Sørland Line and the Bergen Line; in addition, the Airport Express Train operates from Asker to Oslo Airport, Gardermoen. During night, freight trains also use the line.

Anna Paulsdatter Krefting née Vogt (1683-1766), was a Norwegian businesswoman who ran and expanded her family's business enterprises in and around Christiania for over 50 years. Among these enterprises were mines and ironworks, forestry, and trade.Anna Paulsdatter Vogt was born into an affluent family in Christiania with ties to the government in Copenhagen. Her father, Paul Pedersen Vogt, was originally from Denmark and was responsible for the stores at Akershus Fortress but also a merchant, mill owner, and shipowner in Christiania. Anna's mother, Catarina née Bauman, was the daughter of Dominicus Brau(n)man, war commissary and also in charge of the stores at Akershus.Anna married Herman Krefting on 26 October 1699, when she was only 16 years old. The couple had at least seven children together. Anna was widowed while she was pregnant with the last child. She never remarried but took over the business and real estate interests of her husband and managed them for 54 years. In particular, the ironworks at Bærums Verk grew to be the largest of its kind in Norway during her time. But she was also responsible for purchase and sale of land, other ironworks, and mines.She also established a school for the children of her employees and contributed heavily to Tanum Church. She was in continuous litigation with count Ferdinand Anton Danneskiold-Laurvig over rights to mine iron ore on her property on the island of Langøy outside of Kragerø. In 1719 she and her son-in-law Andreas Walleur were granted exclusive rights by the crown to run the iron works at Dikemark. When Walleur died, Krefting let her widowed daughter Anna Katarina run the works. In 1762, the main building burned down at Bærums Verk, but Krefting managed its reconstruction. Since none of Krefting's descendants were interested in taking over her work, the property and holdings were sold on auction upon her death in 1766.Krefting's holdings were visited by two kings, Frederik IV in 1704, and Christian VI in 1733.Krefting also resisted the invasion by Charles XII of Sweden during the Great Northern War in 1716 by notifying Norwegian forces of the Swedish troops' dispositions.
