The Lapponia was an express passenger train operated by the Finnish State Railways, the predecessor of the current national rail traffic operator VR Group. The Lapponia trains operated on a direct route from Oulu via Seinäjoki and Tampere to Helsinki. Southbound Lapponia trains departed from Oulu at 7:00am, arriving in Helsinki at approximately 2:00pm. The returning northbound train left Helsinki at 4:00pm, arriving in Oulu at 10:45pm.
The Lapponia express train service began in 1974 as a fast and direct connection between Oulu and the nation's capital. In the beginning the trains had a maximum allowed speed of 120 kilometers per hour (74.5 miles per hour), but it was increased to 140 km/h (87.0 mph) in sections where the electrification was completed.
The Lapponia trains ran under that name until 1994 when Finnish State Railways discontinued the use of train-specific naming. More or less the same time express passenger trains were superseded by intercity train service.
