The West Highland Line is the most beautiful railway line in Scotland. The train passes over breathtaking landscapes along the formidable looking Glenfinnan Viaduct. The locomotive leaves a billowing trail of white steam as it snakes along the single track railway line 100 feet above the shadowy green scenery below.

Beijing Suburban Railway Line 2 is the so-called most beautiful railway line in China. High-speed trains travel through a sea of blossoming trees near the Juyongguan Great Wall at Juyong Pass, a stop along the railway line. So the line is also called "a journey to the spring days".
