Just one more subway to add on my list.
It is one of the oldest and most extensive public transportation systems in the world, with 468 stations in operation (421, if stations connected by transfers are counted as single stations).
Overall, the system contains 209 mi (337 km) of routes, translating into 656 miles (1,056 km) of revenue track; and a total of 842 miles (1,355 km) including non-revenue trackage.
Stations are located throughout the boroughs of Manhattan, Brooklyn, Queens and the Bronx. While Staten Island does have a rail line, the Staten Island Railway, it is not officially considered part of the subway. In addition, the Staten Island Railway does not connect to any other trains, so any passengers wishing to visit another borough must take a ferry or bus.
