There are also different fares which correspond to the length of time for which the tickets are valid. These fares, with a set time established on the ticket, permit the unlimited use of the Tren Urbano and the buses of the AMA. There are four types of ticket in this category. The first offers an unlimited service for one day and costs $ US . One can add to this a weekly pass for $ US , a 30 day pass for $ US , or, the most extensive, a 90 day pass for $ US . These can be obtained from ticket machines located throughout the system and can be paid for with cash, debit cards, or Visa and MasterCard.
In 1989, Puerto Rico’s Department of Transportation and Public Works (DTPW) proposed to build a mass-transit system called Tren Urbano. This is Puerto Rico’s first mass transit project. Phase one of Tren Urbano is designed to bring a new mode of transportation to the most congested sections of the San Juan Metropolitan area. It will transport passengers in San Juan, capital of Puerto Rico, and the surrounding urban areas. The initial phase of Tren Urbano will serve three central municipalities of the SJMA, Bayamóón, Guaynabo, and San Juan. In 1996 the scheme was projected to cost an estimated $ billion, by 2002 the cost had risen to $ billion.
