BART swings apart from Metro system

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.
