Metrorail’s six lines are so easy to remember that most Washingtonians have memorized them. Here are five convenient bus lines that everyone in town should know just as well.

These five lines are among Metro’s most convenient and popular. Buses on them come every few minutes, and follow easy-to-remember routes along major streets.

For the sort of Washingtonian who’s comfortable with Metrorail but hasn’t taken the leap to the bus, these five lines are a great place to start. Unlike some minor buses that only come once every half hour, you can treat these five lines the way you’d treat a rail line, or a DC Circulator: They’re always there, and it’s never a long wait before the next bus.

If you can memorize Metrorail’s Red and Orange Lines, you can memorize these streets:

Wisconsin / Pennsylvania (30 series): If you want a bus on Wisconsin or Pennsylvania, just remember to catch anything with a number in the 30s. Nine bus routes cover this line, each of them with slightly different details, but a similar overall path: The 30N, 30S, 31, 33, 32, 34, 36, and the express 37 and 39. Collectively they’re called the “30 series.”

The other four lines are similar. Each has multiple routes with slightly different details combining to form a family, or series. Within each series some individual routes may come at different times of day, or continue farther beyond the lines this map shows. But the key is to remember the series name.

16th Street (S series): Four routes, each beginning with the letter S: The S1, S2, S4, and the express S9.

14th Street (50 series): Three routes, each in the 50s: The 52, 53, and 54.

Georgia Avenue (70 series): Two routes, in the 70s: The local 70 and the express 79.

H Street (X series): Two routes, starting with X: The local X2 and the express X9. When it eventually opens (knock on wood), the DC Streetcar will beef up this same corridor.

For the Metrobus veterans among you, this is old news. About 80,000 people per day ride these five lines, so they’re hardly secrets. But if you’re not a frequent bus rider, give these a try.
