Desert Express

Short answer: Railways across deserts such as the Sahara, the Arabian Peninsula and the Australian outback carry freight and ore across arid regions but face blowing, abrasive sand.

Lines may be built on raised ballast beds so sand blows across, sand fences and barriers are placed along exposed stretches, and crews clear drifts from the track. The footage shows the view from the front of a train as it runs over sand-covered rails.
