Going Underground: The Subway

Large cities have very efficient subway systems.  Taking these trains can get you just about anywhere in the city, and you don’t have to wait outside in the rain!

At some stations, there may be people singing or playing a musical instrument. This can be an entertaining way to wait for the train – unless the singer isn’t very good, haha. For most subway systems, you will need a token or farecard.  You can buy these right at the station, either a token booth or at the ticket machine.  You can put dollars or credit cards right into the machine.  It will give you a farecard in the amount you choose.  To get onto the platform, slide the card into the card reader or put a token into the slot.  Then push through the turnstile and hop on the train!
