This is probably the most special way to view the city, it's a metro and functions as such, but it's always above the surface of the earth, and most of the time, it's high up in the air! It is very interesting to see the image of cars way down on the streets and a train overhead. And it works like a well-oiled machine; fast, punctual and not very expensive. Two things that attracted a lot of attention: almost all trains were painted with ads, as well as the strict upbringing of the Thai people waiting for a train. The ground is marked where the train doors will stop and they wait in line at the sides.
