The C Line is a Regional Transportation District (RTD) light rail line that serves stations in Denver, Englewood, Sheridan, and Littleton, Colorado. The line began service on April 5, 2002, coinciding with the opening of the Central Platte Valley Spur along the Southwest Line. It is colored orange on system maps.
The line did not operate between 2021 and 2026, when it was suspended as a result of the COVID-19 pandemic and then restored as a part of two separate RTD service changes which re-configured service on the Southwest Line.
