America's approach to urban transit is a patchwork of systems, philosophies, and levels of investment that varies dramatically from city to city. New York's subway is in a class by itself — 472 stations, round-the-clock service, and a daily ridership that dwarfs every other American transit system combined. But beyond New York, the picture becomes much more interesting and much more varied.

Boston's T is the oldest subway in America, having opened in 1897. Chicago's L is famous for its elevated Loop that circles the downtown core. San Francisco's BART crosses under the bay to connect the East Bay to the peninsula. Washington's Metro was designed as a sleek, modern alternative to the aging Northeastern systems. Atlanta's MARTA serves the sprawling metro area of one of the South's largest cities. Each system reflects its city's unique geography, demographics, and political priorities.

Some of America's most innovative transit solutions are found in unexpected places. The Las Vegas Monorail runs along the Strip, serving tourists in a city not known for public transportation. Miami's Metromover offers free rides through downtown — a rarity in American transit. Seattle's Sound Transit has been one of the fastest-growing light rail systems in the country, expanding rapidly to serve a booming tech-economy population.
