What triggers a fine?
Passengers must always have proof-of-payment to show during ticket inspection.
Fines will be issued to travellers who do not have stamped tickets or in other ways do not hold valid tickets, have failed to activate electronic tickets, or are unable to show a valid mobile phone ticket upon inspection.
Penalties are set by the Norwegian Ministry of Transport and Communications.
Purchase and activation of electronic tickets must be completed before boarding the train. All types of mobile phone tickets must be purchased and activated prior to boarding the train.
