Light Rail Maintenance and Repairs

UPDATE: February 21, 2025

The length of speed restrictions in Slow Zone #3 were significantly reduced this week following the completion of overnight maintenance repairs. Customers along the H and R lines will now notice improved travel times between the I-225 junction and Nine Mile Station.

Inclement weather on Tuesday, February 18, impacted RTD's scheduled plans to complete rail grinding that was focused on removing the last remaining speed restriction in Slow Zone #1. That work will be rescheduled in the coming days when weather conditions are more favorable. Rail distribution, track replacement, railhead grinding, and other maintenance repairs will continue in Slow Zone #3 will continue during the next seven-day period.

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 D, E, H, and R line trains traveling along the Southeast Corridor. The 10 mile-per-hour speed restrictions were 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.
