Madrid's subway is one of the world's densest, having expanded at Asian speeds (50km in six years) to an especially large scale given Madrid's relatively small size (around 3.5 to 6 million). In addition to fast, reliable, and frequent rides, the subway features stations that run the gamut from quaint to spacious to sexy. Newer stations include natural-like lighting and ample entryways. The system also boasts environmentally friendly cleaning -- and one of the coolest subway ad campaigns we've seen.
