Where the railway enters the midnight sun
The Nordland Railway runs north from Trondheim to Bodø, crossing the Arctic Circle on the Saltfjellet mountain plateau. That crossing is more than a map marker: in summer, it takes the train into a region where the sun can remain above the horizon at local midnight.
The effect comes from Earth’s tilt. During northern summer, the Arctic leans toward the sun, and the sun traces a path so high across the sky that it does not dip below the horizon in places north of the Arctic Circle. The farther north you go, the longer this stretch of continuous daylight lasts; near the Circle, it is a relatively short seasonal window.
A landscape that changes with the light
The route climbs through forests and valleys before reaching the open, high ground of Saltfjellet. In the bright season, the shift is not simply from day to night as the train moves north. Instead, the light changes angle and color, while familiar cues—darkness, streetlights, a clear “bedtime” sky—may fail to arrive.
The midnight sun is seasonal, not a permanent feature of the railway. As Earth continues its orbit, the northern region tilts away from the sun again, and ordinary nights return. But during the summer window, a late view from the train can look like afternoon even when the clock says otherwise: the sun is still hanging above the horizon beyond the Arctic Circle.
