There are some who say that less is more, but not so in rapid transit circles. After all, to move the almost 4 million people who call Los Angeles home, one would need a more substantial mass-transit railway than the six lines we have today. And yet, in the same vein as their predecessors in the Pacific Electric (PE) and Los Angeles Railways (LARy), the Los Angeles County Metropolitan Transit Authority (or LACMTA, just the "Metro" for short) continues to provide the best possible service in a county both supportive, disappointed, and downright hostile to its light rail and subway systems. On today's Trolley Tuesday, we take a brief look at each line and what makes it special after discussing their origins last week, so please grab your TAP card, mind the doors, and enjoy a ride on the Metro!
