Subways operate 24 hours. Plenty of people ride the subway at night, but it s safer during the day. If you ride at night, wait for the train in the designated off-hours waiting area and board a car that has other riders. The card is good for free transfers anytime within two hours of swipe. You can purchase cards for different numbers of rides and time periods.
Monthly passes are also available.
The MetroCards are sold at many subway stations, news shops, delicatessens and bodegas. The yellow medallion taxis are the only ones authorized by the city to pick up passengers on the street. The airports, many hotels and some restaurants have taxi stands, but you may hail yellow cabs on any street. One fare covers all passengers. It s always a good idea to ask for a receipt when paying the receipt will have the cab identification number, which will help if you ve left behind an umbrella or shopping bag.
