In 1969, ridership increased by 10 percent and by 12 percent the following year. In 1971 and 1972, it saw a 20-percent increase—the latter representing the first year with InterRail tickets. By then the annual ridership had reached 175,000. In 1970, an additional train was stationed at Flåm, which made it possible to travel a round trip between Flåm and Bergen in a day. Between 1975 and 1982, NSB started running direct trains between Ål and Flåm. In 1978, the morning express trains on the Bergen Line started stopping at Myrdal, allowing better access for tourists to the Flåm Line. Traffic increased further until 1980, when it hit 200,000, and then remained stable through the decade.
