The landscapes along this corridor is diverse, from desert, grassland, to plateaus.
The most terrible thing is the strong wind. Years ago, a slow train was blown upside down.
Sand itself is nothing, u just elevate the railway.
Under no circumstances should a railway be built like that Saudi version, unfenced, no wind/sand control.

@Nan Yang look at the anti-wind/sand efforts along the railway
Thanks. I am actually aware of a highway that China built right in the Taklamakan desert and the decades and decades of effort to plant grass along its entire length. Very costly and never ending.
For five years the government experimented with various plants that could survive desert conditions. In 1999, a pilot project of sand protection afforestation belt along a 6.3-kilometer section of the highway was completed. In 2001, the project was expanded until a 30.8-km stretch along the highway was afforested. The project was finally approved by the state in 2003. Today, nearly four-fifth of the highway is flanked by 72 to 78 meter-wide tree belt, covering a total area of more than 3,000 hectares.
It will be interesting to see how Spain will solve these shifting sand problem. If they can't, the entire railway will not be economical.
