The Blue Line operates from downtown Los Angeles south to
Long Beach on a route that is about 22 miles long. The underground
terminal in L.A., beneath Flower St., is called 7th St./Metro Center; but the
train's destination sign reading "Los Angeles" has a more worldly appeal to it.
Light rail is operated by the Los Angeles County Metropolitan Transportation
Authority, which is known as Metro. The agency also
runs the Red and Purple subway lines and an extensive bus system that
serves much of the most populous county in the
country by far, at close to ten million people.
