Glass Walls Make Sense on the Subway. Let’s Do it.

From Today’s New York Daily News. “It’s called platform screen doors. London has them on some lines. So does Paris. Seoul has them, and Shanghai has them. In fact, they are common now in metro systems all over the world.

Platform screen doors are glass walls between you and the dangerous tracks in the open pit. When a train enters the station, it lines up with the glass doors, which open to let the passengers in and out.”
