Light Rail Maintenance and Repairs

UPDATE: April 25, 2025

To date, 28 of last year’s 29 speed restrictions have now been fully removed from the system.
In early April, RTD updated its maintenance timeline to target lifting all remaining speed restrictions next month.
RTD's weekly status report has been added to this webpage.

Maintenance and Repairs

Preventative maintenance and isolated track repairs are underway across RTD's light rail system. As repairs are made, speed restrictions will continue to be lifted. The resumption of normal train speeds is dependent on how quickly repairs are made to the isolated sections of track.

Speed Restrictions

Light rail speed restrictions are in place for E and H line trains traveling across RTD's network. Many of the 10 mile-per-hour speed restrictions were first implemented on June 4, 2024, and will be in place until crews complete the necessary preventative maintenance. As repairs are made to isolated sections of track, speed restrictions will continue to be lifted.

Light Rail Inspections

RTD conducts regular inspections of its entire light rail system. The intent of inspections is to identify preventive maintenance that may need to be addressed in the near-term or future. This proactive approach allows the agency to ensure all rail assets are in a state of good repair.
