Euromed was a high-speed rail service which uses series 101 EMU rolling stock with bogies adapted for use on the 1,668 mm (5 ft 5 21⁄32 in) Iberian gauge track. Traction current is supplied by overhead lines, at either 3,000 volts direct current, or 25,000 volts alternating current at 50 Hz. In normal commercial service these trains travel at 200 km/h (120 mph) and have a top speed of 220 km/h (140 mph), although 250 km/h (160 mph) was reached during testing. The fleet of six units was built by the French multinational Alstom. In 2009 all the TGV based rolling stock was converted to standard gauge and replaced by the new RENFE Class 130.
Euromed entered commercial service on June 16, 1997, operated by RENFE, along a 523 km (325 mi) Mediterranean corridor, between the cities of Barcelona, Tarragona, Castellon de la Plana, Valencia and Alicante.
On 30 March 2002 a Euromed train traveling across points at 155 km/h (96 mph) collided with a local train in Tarragona that had just left Torredembarra station. The impact caused both trains to derail, two fatalities, and 90 injured.
