Beginning Saturday, Oct. 22, customers will board A Line trains on Track 2 at 38thBlake, 40thColorado and Central Park stations while crews work on Track 1 at the Dahlia Street crossing. Check station platform signs or visit RTD’s Service Disruptions page for more information.

The A Line normally serves stations every 15 minutes, but RTD has changed that frequency to every 30 minutes as trains operate on a single track around the work zone. Regular, 15-minute service on the A Line is scheduled to resume on Thursday, Nov. 10.

Trains will pass workers and equipment on or near the tracks at the Dahlia Street crossing Monday through Saturday during working hours, which begin at 7 a.m. and continue through 3 a.m. the following day. As a safety precaution, train horns will sound through the Dahlia Street crossing during working hours.

Repairs are expected to provide a long-term fix that improves the way trains operate through this section of rail.
