Spain's national RENFE rail network also serves Asturias well; trains regularly depart to and from the Spanish interior. Major stops are the regional capital, Oviedo, and the main coastal city, Gijón. Meanwhile, the FEVE rail company links the centre of the region with Eastern and Western Asturias. Under the Cantabrian Mountains, the Pajares Base Tunnel, is currently under construction, and will reduce the journey times from Madrid to Asturias from 5 hours to just 3 hours, paving the way for the arrival of AVE trains in the near future.
