The Skaugum Tunnel (Norwegian: Skaugumtunnelen) is a 3,790-meter (2 mi) long railway tunnel in Asker, Norway, on the Asker Line. The tunnel runs between Asker Station and Solstad and was built as part of the first stage of the Asker Line, between Asker and Sandvika. Construction started in February 2002 and the tunnel opened on 27 August 2005. The tunnel was built by Mika for the Norwegian National Rail Administration using the drilling and blasting method with one crosscut. During construction there was one blasting accident. Since the tunnel opened, there have been problems with leaks damaging the infrastructure. The tunnel has double track, is electrified and allows for a maximum speed of 160 kilometers per hour (99 mph). The cost to build the tunnel, excluding the infrastructure, was 450 million Norwegian krone (NOK). The tunnel has accelerated intercity and regional traffic west of Oslo and freed up capacity for the Oslo Commuter Rail on the old Drammen Line.

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.

The tunnel has double track, is electrified and allows for a maximum speed of 160 kilometers per hour (100 mph).
