>Yes you do. If the rail goes across any freehold, you'll have to negotiate and compensate for the owners loses. This process takes years if not decades. The only reason China is able to build so quickly is because the government tramples on people rights Actually the Chinese government builds a lot of the high speed rail tracks on elevated tracks in order to avoid interfering with the owner. Which is why most of it…
Perhaps a better photo to make your point: http://en.people.cn/n3/2016/0229/c90000-9022441-11.html So it does seem like they're using tracks elevated by concrete pillars pretty widely, but are you sure your image shows a high-speed rail track? To my untrained eye that seems like a really aggressive curve radius for a high speed rail track. See also: https://en.wikipedia.org/wiki/Minimum_railway_curve_radius#L...
Neither your or your parents photo represents "elevating the rails to avoid interference with the property below".
What's happening in these photos is that either there is a flood plain below the tracks and/or there is a maximum grade (elevation) change that they need to respect and so they are "flattening" the track with those pillars.
Those pillars are not there to be nice, they're there because of physical constraints.
