# C-3 (Cercanías Madrid)

The C-3 is a line and rail service of Cercanías Madrid commuter rail network, operated by Renfe Operadora. It runs from El Escorial northwest of Madrid to Aranjuez south of Madrid. The C-3 shares tracks for half of its length with Madrid commuter rail service line C-8 while it also shares significant parts with lines C-4, and C-7. The line has been in operation since 1980, with its current incarnation in operation since 22 September 2011.
On 5 November 2018, the C-3a service was introduced as a separation of former extended C-3 services terminating at either El Escorial or Santa María de la Alameda. The C-3a designation was formerly used for the now-closed Pinto–San Martín de la Vega branch line (es:Línea Pinto-San Martín de la Vega) branching off from Pinto to Parque Warner Madrid and San Martín de la Vega, which operated between 2002 and 2012.
