In 2007, Madrid's metro system was expanded, and it currently runs over {{convert|322|km|mi|sp=us}} of line. The province of Madrid is also served by an extensive [[commuter rail]] network called [[Cercanías]].

Metro fees are regulated by the [[Consorcio Regional de Transportes de Madrid]] (CRTM) jointly with fees for commuter rail, bus transport and light-rail.
