The reason for this is low price flights from larger relatively nearby airports like Örnsköldsvik Airport and Sundsvall-Timrå Airport and the 5-hour train connection to Stockholm (started 2012) (travel has not been reduced overall during this period, but Kramfors passengers have to a large extent chosen other routes).
