The Metrorail in Washington, D.C.

Built in 1976, it was designed with the vision that it would be a regional transit system, since most folks live outside the core.

This subway is twice the length of our TTC, and is the second busiest in the United States.

The Metrorail, as it’s called, has a zero-tolerance policy of food and trash on the system. This philosophy also extends to the use of station restrooms. The Transit Police have a reputation for enforcing these laws rigorously. One widely publicized incident occurred in the year 2000 when police arrested a 12 year-old girl for eating chips in the Tenleytown Station.

Only in America, eh?
