Sources: 17. Developments: 2. Major railway infrastructure projects are being undertaken in Europe to modernize high-speed lines. In Germany, the Nuremberg-Ingolstadt line in Bavaria underwent a six-week complete closure starting October 30, 2026, for a 70 million euro renovation to replace rails in use since 2006. This project caused significant disruptions for regional and long-distance ICE services, necessitating bus replacements and diversions via Augsburg and Donauwörth. In Spain, the Ministry of Transport is evaluating a potential two-year complete closure of the Madrid-Barcelona high-speed line to facilitate similar modernization efforts. The proposed upgrades include installing aerotravesas to enable speeds of 350 km/h, upgrading signaling systems to ERTMS level 2, and constructing new stations. While the government cites safety and modernization as drivers, regional leaders in Catalonia and the People's Party have expressed concerns regarding service disruptions and socio-economic impacts. ## Timeline ### 2026-11-03: Spain considers two-year closure of Madrid-Barcelona high-speed rail line Spain is considering a two-year closure of the Madrid-Barcelona high-speed rail line for a complete infrastructure overhaul to improve safety and reduce travel times. 4 sources. https://clstr.news/cluster/spain-considers-two-year-closure-of-madrid-barcelona-high-speed-rail-line ### 2026-10-30: Nuremberg-Ingolstadt high-speed rail line to close for six-week renovation The Nuremberg-Ingolstadt high-speed rail line will close for six weeks starting October 30th for a 70 million euro renovation, causing significant delays and requiring replacement buses. 13 sources. https://clstr.news/cluster/nurembergingolstadt-high-speed-rail-line-closed-for-70-million-euro-renovation --- Cite as: European high-speed rail infrastructure renovations.
