The high-speed train that zooms across the Saudi desert

In some countries, high speed trains are treated as if they were alternative transportation of airplanes.
Saudi Arabia must be one of them. That's because the trains has economy class and business class, and
meal set is designated and is served by a uniformed attendant out of an airplane-style beverage cart.
But, the most important difference is that we can ride on high speed train few minutes before departure, because there is no baggage inspection. (Mainland China is exceptional, but it doesn't require as long a preparation time as airport requires)
