The D Line—also referred to as the Green Line, because green is the line's color 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 the first line in the system since it opened in 1994 from downtown Denver to I-25 and Broadway as the Central Corridor. It was extended along the Southwest Corridor in July 2000. Until the Central Platte Valley Spur opened on April 5, 2002, this line had no letter or color designation.

The D Line's northern terminus is in Five Points northeast of downtown Denver. It goes through downtown, running southwest along Welton Street, then going up 19th Street. On trips leaving downtown, the line goes along Stout Street and 14th Street; on trips from Littleton, the line runs along California Street. Then the line follows Stout Street and Colfax Avenue, and follows a railroad right-of-way, where it joins with the C Line at 10th/Osage Station. They run in tandem until they reach their southern terminus at Mineral Avenue in Littleton.

Stations

Note that the Convention Center/Performing Arts Station, which opened in 2004, replaces the 14th/Stout and 14th/California stations, which opened in 1994.

The 2004 voter approved FasTracks plan will add 2.5 mi (4.02 km) to the Southwest Corridor (C Line and D Line). It will also add a station with 1,000 parking spots at C-470 and Lucent Boulevard in Highlands Ranch. There may also be a station at C-470 and Santa Fe Boulevard. Upon opening, the D Line will no longer run to 30th/Downing and all trains will return south via the downtown loop. This extension may open as soon as 2017.
