In 1990, a fast ferry service was introduced in Sogn with direct services to Bergen. In 1991, the Gudvangen Tunnel opened, giving Flåm a road connection to Gudvangen and terminating the ferry service. NSB was losing money on the line, in part because of very low revenue per rider. The same ticket prices were charged as elsewhere, based on a fee per kilometer; the low speed combined with a lot of free travelers using InterRail tickets gave little revenue. From 1991, the ticket prices were increased as if the line was longer. In 1992, a new station building was taken into use at Flåm. During the 1990s, X10 commuter trains from Stockholm were borrowed during the summer for extra trains. These trains had larger windows than Class 69, giving better views. A museum and documentation center was established in 1995. Originally located in an annex of Fretheim Hotel, it moved in 1999 to the old station building at Flåm.
