The FFOO Line 21 (Ferrocarriles Orientales "Blue Line O21") is a commuter rail line in metropolitan Villa Constitución, DF in the Ardisphere. It is part of the integrated RUTA-VC system, and runs from the main FFOO terminus at the Estación Calle 29 to the eastern suburb of Colofón, DC at the foot of the Sierra de los Cientoocho.
The modern line 21 is one of the oldest commuter railroad lines in the Ardisphere, dating in form similar to its current one from the 1890s. Many of the communities along its route are historic "railroad leapfrog suburbs", including many areas later annexed by the growing city such as Barrio Kanguro (Parque Anexo), Lago Sur, Cincuenta por Cientosetenta, and Girasoles.
The route runs in a generally easterly direction starting on the eastern edge of the downtown area, proceeding northeastward to Lázaro, then eastward to Persiles, thence northeastward again to Lago Sur, and then eastward with a slight bend southeast all the way to Araby. Finally it angles northeastward, crosses the Río Hierro at Ciudad Equis, and ends at the foot of the mountains at Colofón.
