Watch a train run over a market (Everyone’s fine! They do this every day!)
Talk about dense living! At the Maeklong vegetable market in Thailand, retail and transportation are closely connected — like, really closely. The vendors lay out their wares so close to the train tracks that when the train comes through, it's literally sitting on top of the produce. Everyone just sort of puts up their awnings and steps aside for a second, and then once the train has passed through they go back to normal.
It's awesome until you think too hard about eating those vegetables. Let's just imagine that the train's underbelly is coated with delicious rosemary.
