The C Line – also referred to as the Orange Line, because the line is colored orange on maps – is a light rail line which is part of the light rail system operated by the Regional Transportation District in the Denver-Aurora Metropolitan Area in Colorado. 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 Mineral Ave. 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 Mineral Ave. 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.
