Tren Urbano
A single line metro connecting Bayamón, Guaynabo and part of San Juan, with stations at office districts, hospitals and malls. It does not reach Old San Juan or the airport, which is exactly what most visitors need. It is clean, cheap and useful for specific trips inside the metro area.
Example
It helps you skip traffic on an inland trip rather than get from the airport to your hotel.
