San Juan

San Juan

San Juan got its first urban rail line in December 2004, when Tren Urbano opened, and full fare service began in June 2005. The line starts in Bayamón to the southwest and runs through Guaynabo, Río Piedras, and the Milla de Oro financial district to Sagrado Corazón in Santurce, about 10.7 miles with 16 stations, and it has not been extended in the twenty years since. In July 2026 Puerto Rico secured about $11 million to study extending the line to Old San Juan and the airport.
