US External Territories Trains and Buses
There are no passenger rail services on American Samoa, Guam, or the US Virgin Islands, but there is a small urban rail system around the metropolitan area of San Juan, Puerto Rico. It is called the Tren Urbano and consists of 16 stations on a single line. Train fares are reasonably priced and tickets are interchangeable with the urban bus system.
Puerto Rico has the most extensive bus system. There is a well-developed bus network here serving the city of San Juan. For travel to other areas of the island, you will need to use your own car or a taxi, or you can opt to use the shared taxi service called publico. Some publicos are cars, while others are 15-seater minibuses. They travel on set routes to many places around Puerto Rico. You can either call them the day before to ask them to collect you from your hotel or you can head to the publico station in Rio Piedras, San Juan, and wait in line for departure.
