Arco is a commercial, locomotive-hauled passenger train service operated in Spain by Renfe on the Levante and Basque Country-Galicia lines.
As of 2021, the Renfe Arco services run on the following routes:
Until 2 May 2008, the trains were operating on the Mediterranean corridor, between Barcelona, Alicante and Murcia. There was also an Arco train service from Porbou / Cerbere (France) and Valencia Nord.
Arco fully renovated and refurbished Renfe's B11x-10200 series of passenger trains. New bogies, capable of working at 220 km/h, were added. The bogies are modified versions of model GC-1 by CAF, also known as GC-3, allowing a higher degree of comfort at higher speeds.
