Miami-Dade Transit's Department of Transportation and Public Works (DTPW) is running Metrorail trains on a single shared track on weekends and after 8 p.m. on weekdays through August 2025, as crews carry out extensive track and guideway safety improvements across the system.

Why is Miami-Dade Metrorail running on a single track?

Miami-Dade Transit's DTPW is conducting single-tracking operations to allow crews safe access to the Metrorail guideway for critical infrastructure upgrades without suspending service entirely. Rather than shutting down lines or segments outright, the agency has chosen a phased approach in which trains traveling in opposite directions share one track, rotating passage to maintain service in both directions.

  • Single-tracking is active every weekend and on weekdays after 8 p.m.
  • Trains continue operating northbound and southbound on the shared guideway.
  • The work is part of broader safety improvement efforts across the Metrorail system.

What should Miami-Dade Metrorail riders expect during this period?

Passengers using Metrorail through August 2025 should expect longer travel times and adjusted headways during single-tracking windows, particularly on weekend trips and late weekday commutes. Because two-way train movement must be coordinated on one track, trains may hold briefly at stations to allow opposing service to clear the shared segment before proceeding.

  • Delays are most likely during the busiest single-tracking windows: weekend daytime service and weekday evenings.
  • Riders should build extra time into any Metrorail trip planned after 8 p.m. on weeknights.
  • Real-time schedule information is available through the GO Miami-Dade Transit app and official rider alerts.

How can Miami-Dade Transit riders stay informed about schedule changes?

Miami-Dade Transit is directing riders to the GO Miami-Dade Transit mobile application and the agency's rider alert system for up-to-date information on single-tracking windows and any resulting schedule adjustments. Both tools provide real-time updates and can help passengers plan around service changes before leaving home or the office.

  • The GO Miami-Dade Transit app is available for download on major mobile platforms.
  • Rider alerts can be accessed through the DTPW's official website and push notification service.
  • Checking alerts before travel is especially important on weekends, when single-tracking may affect the full operating day.

When will normal Metrorail double-track service resume in Miami-Dade?

Miami-Dade Transit's DTPW has indicated that the current single-tracking schedule is set to continue through August 2025, after which the agency expects the safety upgrade work driving the operational change to be sufficiently advanced. The DTPW has not announced a specific end date beyond the August 2025 timeline, so riders should continue monitoring official channels for any updates to the schedule.
