Miami-Dade eyes high-tech buses instead of expanded rail system

Miami-Dade’s mayor admits he’s a recent convert to the cause: pushing Miami to abandon dreams of expanding Metrorail in favor of a new generation of high-tech buses that will make commuters rethink the value of tracks and trains.

Mayor Carlos Gimenez made Metrorail a prominent part of his reelection campaign last year, but on Thursday he ramped up a new transit crusade: winning support for Chinese-made “trackless trains” running on dedicated lanes north and south of Miami.
