Hopeful, because a flat 17 to 45 baht fare across every line would quietly fix one of the most annoying parts of daily life here. Weary, because we have heard a version of this promise before, and the card that was supposed to deliver it has been stuck in limbo for over ten years.

Bangkok does not have one train system. It has several, built at different times, by different bodies, under different contracts. To a passenger, they all look like “the train,” but underneath, they are separate businesses.
