Metro and San Francisco’s BART system are often compared to one another as similar transit agencies.

• Bay Area Rapid Transit has 104 miles of tracks and Metro has 106.
• Both systems began in the 1970s and use similar technologies.
• They also function as a cross between commuter trains with longer trips and subways with short urban hops, using similar pay-for-distance fare models.
• They both shared Richard White as a top leader back in the day.

But one key difference: joie de vivre.
