Montebello is located 6.0 km from Stortinget and was first opened on 15 June 1942.

[1] From 1 July 2006, most of the line to Kolsås, from Montebello station and outwards, was closed for upgrades.

The new station has a longer platform, capable of serving trains with up to six cars, an increase from three.

The previous level crossing has been removed, and a third rail power supply is used throughout.

Up to the upgrade of Kolsåsbanen that started in 2006, trains switched from third rail to overhead wire systems at Montebello.
