Dm3 1213-1237-1214 "Johan" runs through the curves between Katterjåkk and Riksgränsen.
I had my MP3 player rigged at the event. The sound clip can be found at: http://web.telia.com/~u77503725/mp3/Kja-Rgn.mp3 (MP3 file approx 550k). The all-welded track gives a very smooth ride, even when a loaded train passes by. It was fairly windy, which unfortunately affects the recording quality.
