The order is an option from a contract agreed in 2008 initially for 26 commuter and 24 intercity trains, and including an option for up to 100 additional emus. The latest exercised option is worth NKr 1.1bn ($US 193.7m).

The 16 sets are identical to 26 trains from the original order which are currently being introduced on suburban services in the greater Oslo area. The five-car trains have a maximum speed of 200km/h, and have three driving units.
