Tri-Rail

Tri-Rail (reporting mark TRCX) is a commuter rail service linking Miami, Fort Lauderdale and West Palm Beach in Florida, United States. The Tri prefix in the name refers to the three counties served by the railroad: Palm Beach, Broward, and Miami-Dade. Tri-Rail is managed by the South Florida Regional Transportation Authority (SFRTA) along CSX Transportation's former Miami Subdivision; the line is now wholly owned by the Florida Department of Transportation. The 80-mile-long (128.7 km) system has 19 stations along the Southeast Florida coast, and connects directly to Amtrak at numerous stations, to Metrorail at the Metrorail Transfer station, Miami Airport station, and MiamiCentral, and to Brightline at MiamiCentral. In 2025, the line had a ridership of 4,924,100, or about 13,400 per weekday as of the second quarter of 2026. A second Tri-Rail line on the Florida East Coast Railway corridor, dubbed the "Coastal Link", has been proposed. The line would operate between Toney Penna station in Jupiter and MiamiCentral in Downtown Miami, and add commuter rail service between the downtown areas of cities between West Palm Beach and Miami. Combined with the existing Tri-Rail line, this expanded Tri-Rail system is estimated to have a daily passenger ridership of almost 30,000; or approximately 9 million passengers per annum, doubling Tri-Rail's current ridership.
