Service on the C Line is currently suspended due to reduced service levels on RTD, as a result of the COVID-19 pandemic.


The line was added to the system on April 5, 2002, to coincide with the opening of the Central Platte Valley Spur. Initially, C trains operated seven days a week, but ran to Littleton–Mineral station only during peak hours and sporting events. At all other times, C service operated to I-25/Broadway.

On May 3, 2003, C trains began operating to Littleton–Mineral station at all times.

With the opening of the Southeast Corridor on November 17, 2006, weekend C service was discontinued except for certain sporting events, with the new E line operating seven days per week.

On January 11, 2009, the midday service pattern between Union Station and I-25/Broadway was resumed and evening service discontinued.

Midday weekday service was discontinued on January 19, 2012 and was reinstated on August 17, 2014 over the entire route.

The C Line was fully suspended on January 10, 2021 as part of broader service cuts in response to ridership decreases related to the COVID-19 pandemic.[1]


The C Line's northern terminus was at Union Station in Denver, ran on a railroad right-of-way south to its junction with the D Line at 10th & Osage Station, and shared track with the D Line until both lines reach their southern terminus at Mineral Avenue in Littleton.[2]

In addition, the C Line provided access to the sports venues of Denver – Coors Field, Pepsi Center, and Broncos Stadium at Mile HighSix Flags Elitch Gardens, and LoDo, as well as access to the western portion of the Auraria Campus.
