The line is used by the
Cercanías San Sebastián commuter rail line between San Sebastián and Irún, and
Cercanías Madrid lines
C-3,
C-8 and
C-10. Direct Madrid to Irun services often use the
Madrid–León high-speed rail line between Madrid and
Valladolid-Campo Grande and switching to the Madrid-Hendaye line for the rest of the journey as
Alvia services. Various
Renfe Media Distancia services operate on different stretches of track, mostly in
Castile and León, and an Intercity service operates between
A Coruña and Hendaye. The mostly single-track
Casetas–Bilbao railway to
Bilbao-Abando forms a junction with the Madrid–Hendaye route at Miranda de Ebro. At Venta de Baños, the line to
Gijón begins. ==References==
