Central Rail Line and Central Rail Line Extension is the L Line

The 5.3-mile Central Rail Line opened in 1994 and is Denver's first rail line between I-25 & Broadway and the 30th & Downing stations.

The proposed L Line would replace the D Line between the 16th & Stout Station and the 30th & Downing Station, and run on existing track acting as a "loop" around downtown. This proposed change is part of RTD's 2004 voter-approved FasTracks plan to expand transit across the Denver metro area.

Additionally, the future L Line Extension would connect the existing downtown rail service to the University of Colorado A Line from the 30th & Downing Station to the 38th & Blake Station.

About the Project

As part of the August 2017 service changes, it is proposed to separate the operation of the D Line into two lines - the D Line and the L Line.

  • The Welton Street segment would operate as the L Line, as proposed in the Central Rail Extension Mobility Study, and would replace the D Line.
  • The L Line would operate between the 16th & Stout Station and the 30th & Downing Station, with all trains turning at 14th Street.
  • The proposed changes would provide better service on the two different segments, including reliability of service along Welton Street, especially in the northbound direction.
  • Proposed service frequency:
    • Weekday: every 15 minutes 5:00 a.m. – 8:00 p.m.
      every 30 minutes 8:00 p.m. to midnight
    • Weekend: every 15 minutes 8:00 a.m. – 8:00 p.m.
      every 30 minutes 6:00 a.m. to 8:00 a.m., 8:00 p.m. to midnight

Additional Changes proposed on the D Line and C Line

  • The D Line would operate on its current route between the Littleton/Mineral Station and 18th & California, with all trains turning at 19th Street.
    • With the implementation of the L Line, it’s proposed to reduce weekday rush-hour frequency from approximately every 10 minutes to every 15 minutes, and reduce weekday midday service from every 15 minutes to every 30 minutes. The lower weekday frequency would be replaced by the increase in C Line and new L Line service, and four car trains would run during the rush hours.
    • It is also proposed to operate C Line service on weekends and holidays instead of the D Line, frequencies and hours of service would be similar to the existing D Line.
  • These proposed changes will provide improved evening and weekend service to the Union Station area, including airport connections, and events to Coors Field, Pepsi Center and Sports Authority at Mile High Stadium.

These proposed changes are contingent on completion of train and traffic signal construction along the 14th Street loop.

New Rail in New Neighborhoods with the L Line Extension

The Central Rail Extension will connect existing downtown rail service with the 38th & Blake Station on the University of Colorado A Line. The L Line would provide rail service between downtown Denver and the 38th & Blake Station, and act as a “loop” around downtown. The extension will require new track.

Fares

Travel on the L Line would be local fares ($2.60 / $1.30 discounted* ) between the 16th & Stout Station and the 30th & Downing Station. Discount fares apply for those who are eligible.

* Discount fares are available for all seniors 65+, individuals with disabilities, Medicare recipients, elementary, middle and high school students ages 6-19. Children 5 years of age or younger ride free with a fare-paying adult. Active duty members of the U.S. military ride for free on all RTD services. Proof of eligibility is required for all passengers using discounted fare products.

The Central Rail Extension underwent further analysis, including a study to identify the most feasible transit route and operating plan to provide a direct connection between 38th & Blake and downtown Denver.
2014
The Central Rail Extension Mbility Study is complete and provided several options for considerations. Once final funding is identified, final design and construction will begin. In the meantime, basic engineering design started is expected to be 30% complete in 2015.
2015
Basic engineering was completed. Once final funding is identified, final design and construction on the L Line extension will begin.
2017
For the August 2017 service changes, it is proposed to separate the operation of the D Line into two lines. The D Line would operate between the Littleton/Mineral Station and the 18th & California Station.
