Our Nutshell route started with a train ride, leaving Oslo at about 8 a.m. for Myrdal. Our cameras clicked like castanets as the train roared over Norway’s mountainous spine. We travelled through The barren, windswept heaths, glaciers, deep forests, countless lakes, and rugged ski resorts. The railroad is an amazing engineering feat. Completed in 1909, it’s 300 miles long and peaks at 4,266 feet — far above the tree line.
