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 Renfe Feve rail company links the centre of the region with Eastern and Western Asturias. Under the Cantabrian Mountains, the Pajares Base Tunnel, opened in September 2021 only for test trains, is expected to open for commercial servicies sometime in 2023, 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 (high speed trains) in the near future.
