When the line opened, it received a lot of freight traffic for the construction of a power station in Årdal. From the opening, the Flåm Line was the fastest means of transport between Sogn and both Oslo and Bergen, and most post was also sent via the line. From 1977, most of the post was instead sent by truck via Gol, and only post from Aurland went via the railway. Other products sent by the line were milk to the dairy in Voss, which terminated in 1983, as well as fruit. Partial loads saw a large increase during the 1960s, after NSB and the ferry operator Fylkesbaatane i Sogn og Fjordane teamed up to send packages via Flåm to Oslo and Bergen. Flåm had several arrivals until 1973, when Linjegods was established. Following a reorganization, the number of calls was reduced to once per week. Freight volume fell further during the 1980s; an attempt in 1978 to force the three major distributors Linjegods, Firda Billag and Sogn Billag to route traffic via the Flåm Line failed.
