Miami-Dade Commissioner Esteban “Steve” Bovo, head of the commission’s transportation committee, is in discussions with CSX, a railroad company, to use their existing east-west freight line for passenger rail out to western Miami-Dade, either as Metrorail or Tri-Rail.

Bovo told the Miami Herald the talks are going swimmingly, although CSX has not yet confirmed this. The line runs alongside the Dolphin Expressway, running close or relatively close to the Miami Intermodal Center rail hub and a number of other destinations, including Doral, and Florida International University, and since it already exists additional construction to make it passenger-ready would only be about $102 million. That would cover stations and some additional track used for passing, but not cover whatever CSX charged for the line’s usage.
