Class 70 (Norwegian: NSB type 70) is a four-carriage electric multiple unit operated by Vy on medium distance trains around Oslo.

This led to the NSB InterCity Express concept being launched, based on fixed, hourly frequency with upgraded service in new electric multiple units, using higher speeds than traditional trains, and with stops only in the larger towns and cities.

[1] The invitation for the bid was issued on 1 October 1986, and on 20 December 1988 NSB signed a contract with EB Strømmens Verksted concerning the delivery of nine new units.

[1] In 2010, Class 70 became the first Norwegian trains to be installed with wireless Internet, allowing passengers free access on the Lillehammer–Oslo–Skien route.

The chassis is built in aluminum, like the B7 passenger cars, and the units are capable of being multiple driven with the Class 69 and other types of trains.
