CAF Cepia


CAF Sepia is a family of high-speed electric multiple unit trains built by CAF and used in Spain and Turkey. The Sepia is based on the Class 120 high-speed trains manufactured by CAF for the Renfe Operadora (RENFE). The Renfe Operadora was the first to order CAF high speed trains; it ordered 12 of these units in 2001, the Turkish State Railways (TCDD) 12 units. The trains were delivered in 2004 for service. The trains were labelled and marketed as the Sepia by their manufacturer, CAF.

RENFE 120-6051 at Valladolid - Campo Grande (Valladolid)


RENFE ordered twelve units in 2001, and a further 45 units in 2004[7]

29 units of the class RENFE Class 121 were ordered for medium-distance high-speed Avant services. The units are very similar to the Class 120 but include additional electrical equipment for redundancy (a requirement for trains using the Guadarrama Tunnel), and do not provide first class seating, raising the number of seats to 282.
