serving the Downtown Albuquerque, Los Ranchos, and Sandoval County stations. On December 11, 2006, the Los Lunas station opened, and on February 2, 2007, the Belen station opened, extending the line to its southern end. In April 2007, two more stations opened: Bernalillo County/International Sunport on the 20th and Downtown Bernalillo on the 27th. On December 17, 2008, the Isleta Pueblo station opened. Phase II Phase II, the extension of the line to Santa Fe, opened for service on December 17, 2008. Using the existing Santa Fe Southern Railway track from Lamy to Santa Fe, which is filled with sharp curves, would have required the train to slow to 15 miles per hour (24 km/h) in some places, so new tracks were laid to allow travel times comparable to the automobile. The route uses previously existing track from Bernalillo to the base of La Bajada, a hill south of Santa Fe. It then runs on newly built track on a new right-of-way from CP Madrid, for five miles and then in the I-25 median into Santa Fe, at CP Hondo, where it uses an improved Santa Fe Southern Railway track from I-25 to the terminal at the Santa Fe Railyard. Two of the planned stations for the Phase II extension opened on December 17: the South Capitol and the Santa Fe Depot stations. A third station at the NM 599/I-25 interchange in Santa Fe County opened on August 1, 2009. After the opening of the Phase II stations, several more stations opened.

Kewa Pueblo station, serving Santo Domingo Pueblo, opened on March 22, 2010. It is the first station beyond the original 13 planned stations to reach the construction stage and was built using stimulus funds. On September 12, 2009, a special events platform opened for Lobo games service only. At the end of March in 2014, the Rail Runner added security officers to the system. Officers are charged with protecting the trains, inspecting fares, and addressing issues at the stations and parking lots. They are required to wear and use lapel cameras during incidents. Construction of the platform at the Zia Road station, the last of the four planned stations for Phase II, was completed several years in advance of the station's
