There currently is one option to travel by night train from Bergen (Norway) to Oslo (Norway), taking approximately 7 hours: Namely the 606 operated by VY.
VY is Norway's railway company and operates night trains across Norway. Currently, the company operates a route between Oslo and Bergen.
Sleeper compartments feature two beds with good quality mattresses, duvets and pillows. Each compartment is equipped with a sink, mirror, fresh towels, soap and bottled water. The entire compartment must be booked, regardless of whether one or two people are travelling. Up to two adults and two children can share one compartment. Pets are not permitted. Wake-up calls are provided 15 minutes before arrival.
Couchette compartments provide sheets, pillows and blankets which passengers arrange themselves. Each berth includes a reading light, wall storage and USB port. Compartments have two power sockets. Middle and upper berths have fixed safety rails, and ladders are available. Berth sizes vary and are narrower than standard mattresses.
VY offers premium seats that recline completely flat. Seats are angled away from the aisle, providing privacy from other passengers. This is an alternative for those who do not need a separate sleeper compartment. Standard second class seats recline slightly and passengers receive a complimentary night package with blanket, pillow, earplugs and sleep mask.
Breakfast is not included in the ticket price. VY works with hotels in Oslo and Bergen to offer special breakfast rates for night train travelers.
